bd6a7ab187 Add Geofence MVP feature implementation 
Implemented complete MVP for geofencing functionality with database,
backend logic, MQTT integration, and API endpoints.

**Phase 1: Database & Core Logic**
- scripts/init-geofence-db.js: Database initialization for Geofence tables
- lib/types.ts: TypeScript types for Geofence, GeofenceEvent, GeofenceStatus
- lib/geofence-engine.ts: Core geofencing logic (Haversine distance, state tracking)
- lib/geofence-db.ts: Database layer with CRUD operations
- package.json: Added db:init:geofence script

**Phase 2: MQTT Integration & Email Notifications**
- emails/geofence-enter.tsx: React Email template for enter events
- emails/geofence-exit.tsx: React Email template for exit events
- lib/email-renderer.ts: Added geofence email rendering functions
- lib/geofence-notifications.ts: Notification service for geofence events
- lib/mqtt-subscriber.ts: Integrated automatic geofence checking on location updates

**Phase 3: Minimal API**
- app/api/geofences/route.ts: GET (list) and POST (create) endpoints
- app/api/geofences/[id]/route.ts: DELETE endpoint
- All endpoints with authentication and ownership checks

**MVP Simplifications:**
- No zone limit enforcement (unlimited for all users)
- No notification flags (always send Enter + Exit emails)
- Device assignment required (no NULL device logic)
- Circular geofences only

**Features:**
✅ Automatic geofence detection on MQTT location updates
✅ Email notifications for enter/exit events
✅ State tracking to prevent duplicate events
✅ REST API for geofence management
✅ Non-blocking async processing

34f6181e41 Improve MQTT subscriber resilience 
- Remove max reconnect attempts limit (was 10)
- MQTT subscriber now retries indefinitely until connection succeeds
- Reduce log spam by logging only first 10 attempts, then every 10th
- Prevents permanent connection loss after temporary network issues

31c0e1f572 Fix MQTT topic pattern for OwnTracks and implement privacy isolation 
CRITICAL FIX: The OwnTracks app publishes to owntracks/<username>/<device_id>,
not owntracks/owntrack/<device_id>. This was causing data delivery failures
and privacy violations.

Changes:
- Fix ACL topic pattern: owntracks/<username>/# (was: owntracks/owntrack/<device_id>)
- Backend now uses MQTT_ADMIN_USERNAME for global subscription
- Update UI forms and placeholders with correct pattern
- Update email template with correct topic format
- Enable Mosquitto ACL file for user isolation
- Add migration script for existing ACL rules
- Update documentation (README, GEMINI.md)

Privacy & Security:
- Each user isolated at MQTT broker level via ACL
- Backend subscribes with admin credentials to owntracks/+/+
- Web UI filters data by parent_user_id for additional security
- GDPR compliant multi-layer defense in depth

Files changed:
- lib/mqtt-db.ts - Updated createDefaultRule() to use username
- app/api/mqtt/credentials/route.ts - Pass username to ACL creation
- app/admin/mqtt/page.tsx - UI forms and state management
- emails/mqtt-credentials.tsx - Email template topic pattern
- lib/mqtt-subscriber.ts - Use admin credentials from env
- mosquitto/config/mosquitto.conf - Enable ACL enforcement
- README.md, GEMINI.md - Documentation updates
- scripts/fix-acl-topic-patterns.js - Migration script
- MQTT_TOPIC_FIX.md - Detailed implementation guide
