Add offline detection and recovery system (Phase 6)

- Implement OfflineDetector with 5-minute online threshold - Add automatic device scanning (2-minute intervals) - Add offline mode enforcement (disable sync) - Add reconnection handling with priority item processing - Add force reconnect API endpoint - Add comprehensive offline detection tests - Handle device offline/reconnected events
