Fix message display and add voice note debugging

- Fix escaped backslashes in timestamp and sender name display
- Add comprehensive logging for voice note transmission pipeline
- Add peripheral write completion logging
- Track broadcast success/failure for central updates
- Log audio recorder creation and preparation steps
- Better diagnostics for troubleshooting voice note issues
