Fix jwt-token

- Fix drone type 0 handling: check STORE_DRONE_TYPE0 dynamically for test compatibility
- Fix heartbeat response: return 200 instead of 201, update message to 'Heartbeat received'
- Fix validation test: expect 'message' and 'errors' properties instead of 'error'
- Add device creation to heartbeat tests to avoid 404 errors
- Update API paths from /detectors to /api/detectors to match production routing

+# Docker Security Configuration
+
+## Overview
+
+The drone detection system uses a multi-layered security approach with different configurations for development and production environments.
+
+## Security Layers
+
+### 🔒 **Internal-Only Services (No External Access)**
+
+#### 1. PostgreSQL Database
+- **Risk**: Direct database access from internet
+- **Security**: Only accessible via Docker internal network
+- **Development**: Port 5433 exposed via override file
+- **Production**: No external ports
+
+#### 2. Redis Cache/Sessions
+- **Risk**: Session data and cache accessible from internet  
+- **Security**: Only accessible via Docker internal network
+- **Development**: Port 6380 exposed via override file
+- **Production**: No external ports, password protected
+
+#### 3. Data Retention Service
+- **Risk**: System metrics and cleanup data exposure
+- **Security**: Only accessible via management portal with authentication
+- **Development**: Port 3004 can be exposed for testing
+- **Production**: No external ports
+
+#### 4. Backend API (Production)
+- **Risk**: Direct API access bypassing reverse proxy
+- **Security**: Only accessible via nginx reverse proxy in production
+- **Development**: Port 3002 exposed for direct access
+- **Production**: No external ports
+
+### 🌐 **Public-Facing Services (External Access)**
+
+#### 1. Frontend Application
+- **Port**: 3001 (development) / 80 via nginx (production)
+- **Purpose**: User interface for tenant users
+- **Security**: Static files only, no sensitive data
+
+#### 2. Management Portal
+- **Port**: 3003 (development) / 80 via nginx (production)
+- **Purpose**: Administrative interface
+- **Security**: Authentication required, role-based access
+
+#### 3. Nginx Reverse Proxy (Production)
+- **Ports**: 8080 (HTTP), 8443 (HTTPS)
+- **Purpose**: Single entry point for all services
+- **Security**: SSL termination, request filtering
+
+## Configuration Files
+
+### Base Configuration: `docker-compose.yml`
+- **Purpose**: Secure baseline configuration
+- **Security**: All internal services locked down
+- **Database**: No external ports
+- **Redis**: No external ports
+- **Data Retention**: No external ports
+
+### Development Override: `docker-compose.override.yml`
+- **Purpose**: Development convenience
+- **Security**: Exposes internal services for debugging
+- **Usage**: `docker-compose up` (automatically uses override)
+- **Warning**: ⚠️ Never deploy to production with override file
+
+### Production Configuration: `docker-compose.prod.yml`
+- **Purpose**: Maximum security for production
+- **Security**: All services internal-only except nginx
+- **Usage**: `docker-compose -f docker-compose.yml -f docker-compose.prod.yml up`
+- **Features**: Password protection, SSL, enhanced logging
+
+## Deployment Commands
+
+### Development (Less Secure, More Convenient)
+```bash
+# Uses docker-compose.yml + docker-compose.override.yml
+docker-compose up -d
+
+# Direct database access available on localhost:5433
+# Direct Redis access available on localhost:6380
+# Direct backend access available on localhost:3002
+```
+
+### Production (Maximum Security)
+```bash
+# Uses docker-compose.yml + docker-compose.prod.yml  
+docker-compose -f docker-compose.yml -f docker-compose.prod.yml up -d
+
+# No direct database access
+# No direct Redis access  
+# No direct backend access
+# All access via nginx reverse proxy only
+```
+
+### Staging/Testing (Secure but with Monitoring)
+```bash
+# Uses base configuration only
+docker-compose -f docker-compose.yml up -d
+
+# Secure but allows manual inspection if needed
+```
+
+## Security Checklist
+
+### ✅ **Applied Security Measures**
+
+- **Database Isolation**: PostgreSQL not externally accessible
+- **Cache Security**: Redis internal-only with authentication
+- **API Protection**: Backend only accessible via reverse proxy in production
+- **Metrics Security**: Data retention metrics require management authentication
+- **Network Segmentation**: All services on isolated Docker network
+- **Access Control**: Role-based permissions for sensitive endpoints
+- **Audit Logging**: All data retention access logged
+- **Security Headers**: Applied to all management endpoints
+
+### 🔍 **Additional Security Recommendations**
+
+#### Network Security
+- **Firewall**: Configure host firewall to only allow necessary ports
+- **VPN**: Consider VPN access for management interfaces
+- **IP Allowlisting**: Restrict management portal access by IP
+
+#### Database Security
+- **Encryption**: Enable TLS for database connections
+- **Backup Encryption**: Encrypt database backups
+- **User Permissions**: Use least-privilege database users
+
+#### Application Security
+- **JWT Secrets**: Use strong, unique JWT secrets
+- **Session Security**: Configure secure session settings
+- **Rate Limiting**: Enable rate limiting on all endpoints
+
+#### Container Security
+- **Image Scanning**: Scan container images for vulnerabilities
+- **User Permissions**: Run containers as non-root users
+- **Resource Limits**: Set memory and CPU limits
+
+## Emergency Access
+
+### Development Database Access
+```bash
+# Connect to development database (when override is active)
+psql -h localhost -p 5433 -U postgres -d drone_detection
+```
+
+### Production Database Access (Emergency Only)
+```bash
+# Temporarily expose database for emergency access
+docker-compose -f docker-compose.yml -f docker-compose.override.yml up -d postgres
+
+# Connect and then immediately remove override
+psql -h localhost -p 5433 -U postgres -d drone_detection
+
+# Restore production security
+docker-compose -f docker-compose.yml -f docker-compose.prod.yml up -d
+```
+
+## Monitoring & Alerting
+
+### Security Events to Monitor
+- **Unauthorized Access**: Failed authentication attempts on management portal
+- **Data Retention Access**: All access to system metrics endpoints
+- **Database Connections**: Unusual database connection patterns
+- **Network Traffic**: Unexpected traffic to internal services
+
+### Log Locations
+- **Security Logs**: `/app/logs/data_retention_access.log`
+- **Application Logs**: Container logs via `docker-compose logs`
+- **Database Logs**: PostgreSQL container logs
+- **Nginx Logs**: Reverse proxy access logs
+
+This security configuration ensures that sensitive infrastructure components are isolated while maintaining operational flexibility for different environments.

+# Tenant Limits Implementation
+
+## Overview
+
+This document explains how tenant subscription limits are enforced in the UAM-ILS Drone Detection System. All the issues you identified have been resolved:
+
+## ✅ Issues Fixed
+
+### 1. **User Creation Limits**
+- **Problem**: Tenants could create unlimited users regardless of their subscription limits
+- **Solution**: Added `enforceUserLimit()` middleware to `POST /tenant/users`
+- **Implementation**: Counts existing users and validates against `tenant.features.max_users`
+
+### 2. **Device Creation Limits** 
+- **Problem**: Tenants could add unlimited devices regardless of their subscription limits
+- **Solution**: Added `enforceDeviceLimit()` middleware to `POST /devices`
+- **Implementation**: Counts existing devices and validates against `tenant.features.max_devices`
+
+### 3. **API Rate Limiting**
+- **Problem**: No proper API rate limiting per tenant shared among users
+- **Solution**: Implemented `enforceApiRateLimit()` middleware
+- **Implementation**: 
+  - Tracks actual API requests (not page views)
+  - Rate limit is shared among ALL users in a tenant
+  - Uses sliding window algorithm
+  - Applied to all authenticated API endpoints
+
+### 4. **Data Retention**
+- **Problem**: Old data was never cleaned up automatically
+- **Solution**: Created `DataRetentionService` with cron job
+- **Implementation**:
+  - Runs daily at 2:00 AM UTC
+  - Deletes detections, heartbeats, and logs older than `tenant.features.data_retention_days`
+  - Respects unlimited retention (`-1` value)
+  - Provides preview endpoint to see what would be deleted
+
+## 🔧 Technical Implementation
+
+### Middleware: `server/middleware/tenant-limits.js`
+
+```javascript
+// User limit enforcement
+enforceUserLimit() - Prevents user creation when limit reached
+enforceDeviceLimit() - Prevents device creation when limit reached  
+enforceApiRateLimit() - Rate limits API requests per tenant
+getTenantLimitsStatus() - Returns current usage vs limits
+```
+
+### Service: `server/services/dataRetention.js`
+
+```javascript
+DataRetentionService {
+  start() - Starts daily cron job
+  performCleanup() - Cleans all tenants based on retention policies
+  previewCleanup(tenantId) - Shows what would be deleted
+  getStats() - Returns cleanup statistics
+}
+```
+
+### API Endpoints
+
+```bash
+GET /api/tenant/limits
+# Returns current usage and limits for the tenant
+{
+  "users": { "current": 3, "limit": 5, "unlimited": false },
+  "devices": { "current": 7, "limit": 10, "unlimited": false },
+  "api_requests": { "current_minute": 45, "limit_per_minute": 1000 },
+  "data_retention": { "days": 90, "unlimited": false }
+}
+
+GET /api/tenant/data-retention/preview
+# Shows what data would be deleted by retention cleanup
+{
+  "tenantSlug": "tenant1",
+  "retentionDays": 90,
+  "cutoffDate": "2024-06-24T02:00:00.000Z",
+  "toDelete": {
+    "detections": 1250,
+    "heartbeats": 4500,
+    "logs": 89
+  }
+}
+```
+
+## 🚦 How Rate Limiting Works
+
+### API Rate Limiting Details
+- **Granularity**: Per tenant (shared among all users)
+- **Window**: 1 minute sliding window
+- **Storage**: In-memory with automatic cleanup
+- **Headers**: Standard rate limit headers included
+- **Tracking**: Only actual API requests count (not static files/page views)
+
+### Example Rate Limit Response
+```json
+{
+  "success": false,
+  "message": "API rate limit exceeded. Maximum 1000 requests per 60 seconds for your tenant.",
+  "error_code": "TENANT_API_RATE_LIMIT_EXCEEDED",
+  "max_requests": 1000,
+  "window_seconds": 60,
+  "retry_after_seconds": 15
+}
+```
+
+## 📊 Subscription Tiers
+
+The system supports different subscription tiers with these default limits:
+
+```javascript
+// Free tier
+{
+  max_devices: 2,
+  max_users: 1,
+  api_rate_limit: 100,
+  data_retention_days: 7
+}
+
+// Pro tier  
+{
+  max_devices: 10,
+  max_users: 5,
+  api_rate_limit: 1000,
+  data_retention_days: 90
+}
+
+// Business tier
+{
+  max_devices: 50,
+  max_users: 20,
+  api_rate_limit: 5000,
+  data_retention_days: 365
+}
+
+// Enterprise tier
+{
+  max_devices: -1,    // Unlimited
+  max_users: -1,      // Unlimited  
+  api_rate_limit: -1, // Unlimited
+  data_retention_days: -1 // Unlimited
+}
+```
+
+## 🔒 Security Features
+
+### Limit Enforcement Security
+- All limit checks are done server-side (cannot be bypassed)
+- Security events are logged when limits are exceeded
+- Failed attempts include IP address, user agent, and user details
+- Graceful error messages prevent information disclosure
+
+### Error Response Format
+```json
+{
+  "success": false,
+  "message": "Tenant has reached the maximum number of users (5). Please upgrade your subscription or remove existing users.",
+  "error_code": "TENANT_USER_LIMIT_EXCEEDED",
+  "current_count": 5,
+  "max_allowed": 5
+}
+```
+
+## 🕒 Data Retention Schedule
+
+### Cleanup Process
+1. **Trigger**: Daily at 2:00 AM UTC via cron job
+2. **Process**: For each active tenant:
+   - Check `tenant.features.data_retention_days`
+   - Skip if unlimited (`-1`)
+   - Calculate cutoff date
+   - Delete old detections, heartbeats, logs
+   - Log security events for significant cleanups
+3. **Performance**: Batched operations with error handling per tenant
+
+### Manual Operations
+```javascript
+// Preview what would be deleted
+const service = new DataRetentionService();
+const preview = await service.previewCleanup(tenantId);
+
+// Manually trigger cleanup (admin only)
+await service.triggerManualCleanup();
+
+// Get cleanup statistics
+const stats = service.getStats();
+```
+
+## 🔧 Docker Integration
+
+### Package Dependencies
+Added to `server/package.json`:
+```json
+{
+  "dependencies": {
+    "node-cron": "^3.0.2"
+  }
+}
+```
+
+### Service Initialization
+All services start automatically when the Docker container boots:
+```javascript
+// In server/index.js
+const dataRetentionService = new DataRetentionService();
+dataRetentionService.start();
+console.log('🗂️  Data retention service: ✅ Started');
+```
+
+## 🧪 Testing the Implementation
+
+### Test User Limits
+```bash
+# Create users until limit is reached
+curl -X POST /api/tenant/users \
+  -H "Authorization: Bearer $TOKEN" \
+  -d '{"username":"test6","email":"test6@example.com","password":"password"}'
+
+# Should return 403 when limit exceeded
+```
+
+### Test Device Limits
+```bash
+# Create devices until limit is reached  
+curl -X POST /api/devices \
+  -H "Authorization: Bearer $TOKEN" \
+  -d '{"id":"device-11","name":"Test Device 11"}'
+
+# Should return 403 when limit exceeded
+```
+
+### Test API Rate Limits
+```bash
+# Send rapid requests to trigger rate limit
+for i in {1..1100}; do
+  curl -X GET /api/detections -H "Authorization: Bearer $TOKEN" &
+done
+
+# Should return 429 after limit reached
+```
+
+### Test Data Retention
+```bash
+# Preview what would be deleted
+curl -X GET /api/tenant/data-retention/preview \
+  -H "Authorization: Bearer $TOKEN"
+
+# Check tenant limits status
+curl -X GET /api/tenant/limits \
+  -H "Authorization: Bearer $TOKEN"
+```
+
+## 📈 Monitoring & Logging
+
+### Security Logs
+All limit violations are logged with full context:
+- User ID and username
+- Tenant ID and slug  
+- IP address and user agent
+- Specific limit exceeded and current usage
+- Timestamp and action details
+
+### Performance Monitoring
+- Rate limit middleware tracks response times
+- Data retention service logs cleanup duration and counts
+- Memory usage monitoring for rate limit store
+- Database query performance for limit checks
+
+## 🔄 Upgrade Path
+
+When tenants upgrade their subscription:
+1. Update `tenant.features` with new limits
+2. Limits take effect immediately
+3. No restart required
+4. Historical data respects new retention policy on next cleanup
+
+This comprehensive implementation ensures that tenant limits are properly enforced across all aspects of the system, preventing abuse while providing clear feedback to users about their subscription status.

+# Data Retention Service
+
+A lightweight, standalone microservice responsible for automated data cleanup based on tenant retention policies.
+
+## Overview
+
+This service runs as a separate Docker container and performs the following functions:
+
+- **Automated Cleanup**: Daily scheduled cleanup at 2:00 AM UTC
+- **Tenant-Aware**: Respects individual tenant retention policies
+- **Lightweight**: Minimal resource footprint (~64-128MB RAM)
+- **Resilient**: Continues operation even if individual tenant cleanups fail
+- **Logged**: Comprehensive logging and health monitoring
+
+## Architecture
+
+```

+
+## Features
+
+### 🕒 Scheduled Operations
+- Runs daily at 2:00 AM UTC via cron job
+- Configurable immediate cleanup for development/testing
+- Graceful shutdown handling
+
+### 🏢 Multi-Tenant Support
+- Processes all active tenants
+- Respects individual retention policies:
+  - `-1` = Unlimited retention (no cleanup)
+  - `N` = Delete data older than N days
+  - Default: 90 days if not specified
+
+### 🧹 Data Cleanup
+- **Drone Detections**: Historical detection records
+- **Heartbeats**: Device connectivity logs  
+- **Security Logs**: Audit trail entries (if applicable)
+
+### 📊 Monitoring & Health
+- Built-in health checks for Docker
+- Memory usage monitoring
+- Cleanup statistics tracking
+- Error logging with tenant context

+LOG_LEVEL=info          # Logging level
+```
+
+### Docker Compose Integration
+
+```yaml
+data-retention:
+  build:
+    context: ./data-retention-service
+  container_name: drone-detection-data-retention
+  restart: unless-stopped
+  environment:
+    DB_HOST: postgres
+    DB_PORT: 5432
+    DB_NAME: drone_detection
+    DB_USER: postgres
+    DB_PASSWORD: your_secure_password
+  depends_on:
+    postgres:
+      condition: service_healthy
+  deploy:
+    resources:
+      limits:
+        memory: 128M
+```
+
+## Usage
+
+### Start with Docker Compose
+
+```bash
+# Start all services including data retention
+docker-compose up -d
+
+# Start only data retention service
+docker-compose up -d data-retention
+
+# View logs
+docker-compose logs -f data-retention
+```
+
+### Manual Container Build
+
+```bash
+# Build the container
+cd data-retention-service
+docker build -t data-retention-service .
+
+# Run the container
+docker run -d \
+  --name data-retention \
+  --env-file .env \
+  --network drone-network \
+  data-retention-service
+```
+
+### Development Mode
+
+```bash
+# Install dependencies
+npm install
+
+# Run with immediate cleanup
+IMMEDIATE_CLEANUP=true npm start
+
+# Run in development mode
+npm run dev
+```
+
+## Logging Output
+
+### Startup
+```
+🗂️  Starting Data Retention Service...
+📅 Environment: production
+💾 Database: postgres:5432/drone_detection
+✅ Database connection established
+⏰ Scheduled cleanup: Daily at 2:00 AM UTC
+✅ Data Retention Service started successfully
+```
+
+### Cleanup Operation
+```
+🧹 Starting data retention cleanup...
+⏰ Cleanup started at: 2024-09-23T02:00:00.123Z
+🏢 Found 5 active tenants to process
+🧹 Cleaning tenant acme-corp - removing data older than 90 days
+✅ Tenant acme-corp: Deleted 1250 detections, 4500 heartbeats, 89 logs
+⏭️  Skipping tenant enterprise-unlimited - unlimited retention
+✅ Data retention cleanup completed
+⏱️  Duration: 2347ms
+📊 Deleted: 2100 detections, 8900 heartbeats, 156 logs
+```
+
+### Health Monitoring
+```
+💚 Health Check - Uptime: 3600s, Memory: 45MB, Last Cleanup: 2024-09-23T02:00:00.123Z
+```
+
+## API Integration
+
+The main backend provides endpoints to interact with retention policies:
+
+```bash
+# Get current tenant limits and retention info
+GET /api/tenant/limits
+
+# Preview what would be deleted
+GET /api/tenant/data-retention/preview
+```
+
+## Error Handling
+
+### Tenant-Level Errors
+- Service continues if individual tenant cleanup fails
+- Errors logged with tenant context
+- Failed tenants skipped, others processed normally
+
+### Service-Level Errors  
+- Database connection issues cause service restart
+- Health checks detect and report issues
+- Graceful shutdown on container stop signals
+
+### Example Error Log
+```
+❌ Error cleaning tenant problematic-tenant: SequelizeTimeoutError: Query timeout
+⚠️  Errors encountered: 1
+   - problematic-tenant: Query timeout
+```
+
+## Performance
+
+### Resource Usage
+- **Memory**: 64-128MB typical usage
+- **CPU**: Minimal, only during cleanup operations
+- **Storage**: Logs rotate automatically
+- **Network**: Database queries only
+
+### Cleanup Performance
+- Batch operations for efficiency
+- Indexed database queries on timestamp fields
+- Parallel tenant processing where possible
+- Configurable batch sizes for large datasets
+
+## Security
+
+### Database Access
+- Read/write access only to required tables
+- Connection pooling with limits
+- Prepared statements prevent SQL injection
+
+### Container Security  
+- Non-root user execution
+- Minimal base image (node:18-alpine)
+- No exposed ports
+- Isolated network access
+
+## Monitoring
+
+### Health Checks
+```bash
+# Docker health check
+docker exec data-retention node healthcheck.js
+
+# Container status
+docker-compose ps data-retention
+
+# Service logs  
+docker-compose logs -f data-retention
+```
+
+### Metrics
+- Cleanup duration and frequency
+- Records deleted per tenant
+- Memory usage over time
+- Error rates and types
+
+## Troubleshooting
+
+### Common Issues
+
+**Service won't start**
+```bash
+# Check database connectivity
+docker-compose logs postgres
+docker-compose logs data-retention
+
+# Verify environment variables
+docker-compose config
+```
+
+**Cleanup not running**
+```bash
+# Check cron schedule
+docker exec data-retention ps aux | grep cron
+
+# Force immediate cleanup
+docker exec data-retention node -e "
+const service = require('./index.js');
+service.performCleanup();
+"
+```
+
+**High memory usage**
+```bash
+# Check cleanup frequency
+docker stats data-retention
+
+# Review tenant data volumes
+docker exec data-retention node -e "
+const { getModels } = require('./database');
+// Check tenant data sizes
+"
+```
+
+### Configuration Validation
+
+```bash
+# Test database connection
+docker exec data-retention node healthcheck.js
+
+# Verify tenant policies
+docker exec -it data-retention node -e "
+const { getModels } = require('./database');
+(async () => {
+  const { Tenant } = await getModels();
+  const tenants = await Tenant.findAll();
+  console.log(tenants.map(t => ({
+    slug: t.slug,
+    retention: t.features?.data_retention_days
+  })));
+})();
+"
+```
+
+## Migration from Integrated Service
+
+If upgrading from a version where data retention was part of the main backend:
+
+1. **Deploy new container**: Add data retention service to docker-compose.yml
+2. **Verify operation**: Check logs for successful startup and database connection
+3. **Remove old code**: The integrated service code is automatically disabled
+4. **Monitor transition**: Ensure cleanup operations continue normally
+
+The service is designed to be backward compatible and will work with existing tenant configurations without changes.
