Implement RTSP streaming functionality for cameras

- Added endpoints to start and stop RTSP streaming for cameras in the API.
- Enhanced CameraManager and CameraStreamer classes to manage RTSP streaming state and processes.
- Updated API documentation to include new RTSP streaming commands.
- Modified Docker configurations to include FFmpeg for RTSP streaming support.
- Adjusted MediaMTX settings for improved stream handling and timeout configurations.
