Add Docker support (frontend, backend, docker-compose)

[noman-akram29]

Hi Remy,

I’ve added Docker support to simplify running the project:

• Dockerfile for frontend
• Dockerfile for backend
• docker-compose.yml to run frontend and backend together

Additionally, I made a small update in application.py to ensure compatibility with the Docker setup.

With these changes, the project can be run locally with:

"docker-compose up"

This should help with consistent environment setup and make onboarding easier for new contributors.

Please let me know if you’d like any adjustments or improvements!
