feat: wire anomaly detection & security mode API endpoints

- AnomalyDetector initialized and running in main() with periodic updates
- Anomaly events pushed to dashboard WS feed as 'alert' messages
- GET /api/anomalies?since=24h lists recent anomaly events
- POST /api/security/arm + /api/security/disarm endpoints
- GET /api/security/status returns armed, learning_until, anomaly_count_24h
- Arm/disarm state persists via learning_state SQLite table
