Refactor audio capture error handling and cleanup logic

- Removed console logging from the useSystemAudioCapture hook to streamline the code.
- Introduced error handling in the audio capture state to capture and report errors more effectively.
- Updated the cleanup logic to ensure proper handling of errors during audio capture on unmount.
- Enhanced error messages for better clarity when audio capture fails.
