Update Docker Registry URLs to HTTPS endpoint (registry.michaelschiemer.de)

- Replace git.michaelschiemer.de:5000 (HTTP) with registry.michaelschiemer.de (HTTPS)
- Update all Ansible playbooks and configuration files
- Update CI/CD workflows to use HTTPS registry endpoint
- Update Docker Compose files with new registry URL
- Update documentation and scripts

Benefits:
- Secure HTTPS connection (no insecure registry config needed)
- Consistent use of HTTPS endpoint via Traefik
- Better security practices for production deployment
