Adds CI/CD workflow for Docker builds

Implements a workflow that builds, pushes, and runs a Docker container on push to the main branch.

This automates the process of building and deploying the application, ensuring that the latest changes are always reflected in the running container. It also handles stopping and removing existing containers before running the new one.
