Fix voice recording and notification issues

Browse Source 
- Fix mic button gesture handling by removing Button wrapper
  - Use direct gesture on ZStack for more reliable touch detection
  - Add debug logging for recording start/stop

- Fix notification delivery on iOS
  - Change from checking .background to checking != .active
  - Notifications now work when app is inactive or background
  - Add NSUserNotificationsUsageDescription to Info.plist

- Improve voice note fragment transmission
  - Reduce fragment size from 400 to 200 bytes for better reliability
  - Simplify fragment timing from batch-based to linear 100ms delays
  - Lower packet size threshold from 512 to 400 bytes for fragmentation
  - Add peripheral connection state checking before writes
  - Better error logging throughout transmission pipeline

- Add comprehensive debug logging for troubleshooting
  - Log audio file size and duration
  - Log peripheral connection states during broadcast
  - Log fragment send progress with timing info
