feat: Refactor MainController and related tasks to follow Porto architecture

- Moved logic from MainController to dedicated action and task classes.
- Introduced GetMainPageDataAction, GetEducationsDataTask, GetRecentPostsTask, GetUpcomingEventsTask, and GetPageDataTask for better separation of concerns.
- Updated routes to use the new MainController from the Main container.
- Deprecated the old MainController with a clear message for future removal.
- Updated caching mechanisms to use the new task classes.
- Adjusted environment variable access to use config() instead of env() for better practice.
- Added new MainPageResource for structured data response.
- Updated .gitignore to exclude QWEN.md.
- Added Jenkins service to docker-compose for CI/CD integration.
