Enhance OAuth and browser configuration

- Updated `config.py` to include paths for Opera browser and added new OAuth settings for alert display and timeout configurations.
- Modified `oauth_auth.py` to improve error handling and user data directory retrieval for Opera, along with conditional alert display based on configuration.
- Enhanced `utils.py` to support multiple Opera installation paths for better browser detection.
- Updated localization files to include new strings for user data directory messages.
