Enhance camera configuration and auto-recording functionality

- Updated CameraStreamer to configure streaming settings from config.json, including manual exposure, gain, image quality, noise reduction, and color settings.
- Added new methods in CameraStreamer for configuring image quality, noise reduction, color settings, and advanced settings.
- Extended CameraConfig to include manual white balance RGB gains.
- Improved AutoRecordingManager to handle camera status updates and ensure proper recording starts/stops based on machine state changes.
- Created detailed configuration documentation for blower and conveyor cameras, outlining settings and their mappings to config.json.
- Implemented a comprehensive test script for auto-recording functionality with simulated MQTT messages, verifying correct behavior on machine state changes.
