Containerize the project

Add Docker and Docker Compose files to streamline the process of setting up and running the application. By containerizing the app, we can simplify development, testing, and deployment, making it easier for contributors to work in consistent environments without complex setup steps.

## Objectives
- Create a Dockerfile to define the application environment and dependencies.
- Set up a ```docker-compose.yml file``` to manage services, including the main app and any additional dependencies (e.g., database, cache).
- Run the app locally with ```docker-compose up``` command.
- Document the setup instructions in the README for easy adoption by other contributors.
