Fix network notifications and add debugging

- Network notifications now show even when app is in foreground
- Added unique identifiers to prevent iOS deduplication
- Set interruptionLevel to timeSensitive for prominence
- Added comprehensive logging throughout notification flow
- Improved error handling for notification permissions
