Add Celery support for heavy tasks

[n0nuser]

🚀 Feature Request

Is your feature request related to a problem? Please describe.

• The current repository does not support handling heavy or long-running tasks efficiently. This can lead to performance issues and a poor user experience for applications that require background processing.

---

Describe the solution you'd like

• Integrate Celery to handle heavy and long-running tasks asynchronously. This includes:
  • Setting up Celery with the repository to offload tasks from the main application.
  • Configuring Celery to use a message broker like Redis or RabbitMQ.
• Integrate Flower to monitor and manage Celery tasks. This includes:
  • Setting up Flower to provide a web-based UI for monitoring task execution and status.
  • Ensuring Flower can be easily started alongside the main application and Celery worker.

---

Describe alternatives you've considered

• Implementing custom background task handling, which can be complex and less reliable compared to using Celery.
• Using other task queues or job processing systems, but Celery is widely adopted and has extensive community support and documentation.

---

Additional context

• Adding Celery support will significantly enhance the repository's ability to handle resource-intensive and time-consuming tasks without blocking the main application.
• Including Flower provides an intuitive way to monitor and manage tasks, improving the maintainability and reliability of applications built using this repository.
• Providing example configurations and usage documentation for Celery and Flower will help developers quickly set up and utilize these tools.
