fix(deployment): add image references to docker-compose.production.yml

Production deployment was failing because docker-compose.production.yml
had build: sections but no image: references. This caused Docker Compose
to attempt building on the server, which failed because the docker/
directory doesn't exist in the deployment location.

Changes:
- Add image: git.michaelschiemer.de:5000/framework:latest to web, php, and queue-worker services
- Removed build: section from php service (no longer needed)
- Remove test comment from ShowHome.php

The deployment script's sed command (line 1259-1260 in build-image.yml)
now successfully finds and updates the image: tags with the correct
version from the registry.
