Add WebSocket, multi API key, geocoding proxy, beacon map picker, and comprehensive bug fixes

- Multi API Key + permission system (read/write/admin) with SHA-256 hash
- WebSocket real-time push (location, alarm, device_status, attendance, bluetooth)
- Geocoding proxy endpoints for Amap POI search and reverse geocode
- Beacon modal map-based location picker with search and click-to-select
- GCJ-02 ↔ WGS-84 bidirectional coordinate conversion
- Data cleanup scheduler (configurable retention days)
- Fix GPS longitude sign inversion (course_status bit 11: 0=East, 1=West)
- Fix 2G CellID 2→3 bytes across all protocols (0x28, 0x2C, parser.py)
- Fix parser loop guards, alarm_source field length, CommandLog.sent_at
- Fix geocoding IMEI parameterization, require_admin import
- Improve API error messages for 422 validation errors
- Remove beacon floor/area fields (consolidated into name)
