Integrate microphone improvements from k0ffinz repository

- Add experimental microphone loudness detection feature
- Remove microphone restart interval for better stability
- Improve microphone initialization and error handling
- Fix audio delay issues by setting channel_disable_time=0.0
- Update settings UI to include experimental mic loudness toggle
- Add credits to k0ffinz/Ralsi for microphone improvements

These changes improve audio responsiveness and fix various
microphone-related issues including WASAPI errors and growing
audio delay problems.
