Enhance camera recording functionality with streamer integration

- Updated CameraRecorder to support frame sharing from CameraStreamer, allowing for more efficient video recording.
- Modified CameraManager to ensure streamer references are correctly assigned to recorders.
- Enhanced CameraStreamer to include a recording frame queue for concurrent access during recording.
- Improved logging for better tracking of recording states and streamer activity.
- Updated API tests to include new functionality for retrieving video lists.
