Add token refresh functionality and improve token extraction

- Introduced a new `get_user_token.py` file to handle token refresh logic using the Chinese server API.
- Updated `config.py` to include new token settings for refresh server URL and enable refresh option.
- Refactored `oauth_auth.py` to utilize the new token extraction method, enhancing error handling and user feedback.
- Added localization strings for token refresh messages in both English and Chinese to improve user experience.
