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.
