jetson f9e411f407 feat: 15+ FPS live preview via WebSocket push ...

- flask-socketio + threading mode (no eventlet monkey-patching)
- preview_queue in pipeline: downscale to 640p, JPEG encode, bounded queue
- encoder thread per job reads queue → SocketIO broadcast to room
- Frontend: SocketIO client replaces HTTP polling, handles preview_frame event
- Configurable: preview_every_n, preview_max_dim, preview_jpeg_quality
- 62/62 tests pass
