Translate UI to Traditional Chinese

- Created 'lang/zh_TW.json' with comprehensive translations for UI elements, forms, navigation, and messages.
- Updated 'config/app.php' to set locale to 'zh_TW' and timezone to 'Asia/Taipei'.
- This ensures the entire application interface is presented in Traditional Chinese.
