Refactor Dockerfile and CI workflow for improved dependency management and cleanup

- Updated Dockerfile to optimize layer caching by copying requirements.txt before application code.
- Added caching for pip packages in CI workflow to speed up dependency installation.
- Implemented cleanup of dangling Docker images post-deployment.
