WIP: Change DailyNotificationReceiver to exported=true for AlarmManager broadcasts

The DailyNotificationReceiver was not being triggered when scheduled alarms
fired, preventing notifications from appearing at the scheduled time.

Changed android:exported from "false" to "true" to allow AlarmManager
broadcasts to reach the receiver, especially when the app is closed or
the device is in doze mode.

This is a work-in-progress change to diagnose why notifications aren't
firing. The receiver should log "DN|RECEIVE_START" when triggered, but
we were not seeing these logs even when alarms were scheduled.

Next steps:
- Test if receiver is now triggered when alarm fires
- Verify notifications appear at scheduled time
- Consider adding permission check if keeping exported=true for security
