Alireza Vaezi ff7cb2c8f3 Add comprehensive tests for camera streaming, time synchronization, and auto-recording functionality

- Implemented test script for camera streaming functionality, covering API endpoints and concurrent recording.
- Created time verification script to check system time synchronization against multiple APIs.
- Developed timezone utility tests to validate timezone functions and logging.
- Added integration tests for system components, including configuration, camera discovery, and API endpoints.
- Enhanced MQTT logging and API endpoint tests for machine and MQTT status.
- Established auto-recording tests to simulate state changes and verify automatic recording behavior.
- Created simple tests for auto-recording configuration and API model validation.
