Update Docker configuration, enhance error handling, and improve logging

- Added health check to the camera management API service in docker-compose.yml for better container reliability.
- Updated installation scripts in Dockerfile to check for existing dependencies before installation, improving efficiency.
- Enhanced error handling in the USDAVisionSystem class to allow partial operation if some components fail to start, preventing immediate shutdown.
- Improved logging throughout the application, including more detailed error messages and critical error handling in the main loop.
- Refactored WebSocketManager and CameraMonitor classes to use debug logging for connection events, reducing log noise.
