fix(android): add UI-friendly permission status field names

The test app UI expects 'notificationsEnabled' and 'exactAlarmEnabled'
fields from checkPermissionStatus(), but the plugin only returned
technical field names ('postNotificationsGranted', 'exactAlarmGranted').

Added compatibility fields:
- notificationsEnabled = postNotificationsGranted && notificationsEnabledAtOsLevel
- exactAlarmEnabled = exactAlarmGranted

This ensures the UI can correctly display permission status after
granting permissions.
