Added BullBoard to the application to provide a visual interface for monitoring background job queues, accessible on port 3001. The integration utilizes @bull-board/api and @bull-board/express, and includes necessary updates to the Docker setup and port mapping to ensure proper access. This will significantly improve observability and debugging for our queue-based tasks.

We have introduced a robust code-executor service designed for secure execution of user-submitted code in isolated Docker environments. This service leverages BullMQ for scalable task queuing and currently supports 8 major programming languages. Comprehensive deployment guides and API runbooks have been added to streamline integration and management.
