Add Docker Support for Development Environment

[Aryan3522]

To simplify the setup process for contributors, the project should support Docker containers.

What you need to do:

1. Create a Dockerfile for the backend.

2. Create a Dockerfile for the frontend.

3. Add a docker-compose.yml.

Expected services:

frontend
backend
database
redis

Contributors should be able to start the entire project using:

docker-compose up

Explain in your pull request:

• Container structure

• How developers can run the project with Docker
