Enhance media API transcoding and video streaming capabilities

- Added support for limiting concurrent transcoding operations in the media API to prevent resource exhaustion.
- Implemented functions to retrieve video duration and bitrate using ffprobe for improved streaming performance.
- Enhanced the generate_transcoded_stream function to handle HTTP range requests, allowing for more efficient video playback.
- Updated VideoModal component to disable fluid and responsive modes, ensuring proper container boundaries during video playback.
- Improved logging throughout the transcoding process for better error tracking and debugging.
