Enhance bot functionality with new features and improvements

- Added a new `/status` endpoint in `server_prometheus.py` to provide process status information, including uptime and resource usage metrics.
- Implemented a PID manager in `run_helper.py` to track the bot's process, improving monitoring capabilities.
- Introduced a method to delete audio moderation records in `audio_repository.py`, enhancing database management.
- Updated voice message handling in callback handlers to ensure proper deletion of audio moderation records.
- Improved error handling and logging in various services, ensuring better tracking of media processing and file downloads.
- Refactored media handling functions to streamline operations and improve code readability.
- Enhanced metrics tracking for file downloads and media processing, providing better insights into bot performance.
