Fix Dockerfile and run.sh for gunicorn workers (#58)

* Fix Dockerfile and run.sh to resolve 'No module named src' error in gunicorn workers

- Copy src and data directories into container image
- Set PYTHONPATH=/app in run.sh before launching gunicorn

This ensures absolute imports from src.* work in all environments.

* Update run.sh
