Add Docker support for FoodsharingSiegen project

Introduced Docker setup, including `docker-compose.yml`, `dockerfile.server`, and related Python helper scripts (`image-create.py`, `image-push.py`, `publish-project.py`, `publish-aio.py`) for building, managing, and deploying Docker images. Updated `.gitignore` to exclude published files, and renamed a field label in the Blazor component for better clarity.
