Fix startup crash: Delay offline manager initialization by 500ms

- Move init calls from onCreate() to Handler.postDelayed()
- Create OfflineInitRunnable inner class for delayed execution
- Add try-catch wrapper for safety
- Add detailed logging for debugging

This fixes the crash caused by offline managers trying to access
Context/SharedPreferences before Android system fully initializes.
