feat: enhance MediaWiki integration and error handling in SMW client

- Added MediaWiki API configuration options to docker-compose.yml for production environment.
- Improved error handling in the SMW client by introducing a response parsing method to manage API errors more effectively.
- Updated methods in the SMW client to ensure robust handling of API responses, preventing potential crashes due to unexpected data structures.
- Enhanced the import functionality to handle last imported timestamps more gracefully.
