Add comprehensive test suite for USDA Vision Camera System
- Implemented main test script to verify system components and functionality. - Added individual test scripts for camera exposure settings, API changes, camera recovery, maximum FPS, MQTT events, logging, and timezone functionality. - Created service file for system management and automatic startup. - Included detailed logging and error handling in test scripts for better diagnostics. - Ensured compatibility with existing camera SDK and API endpoints.
