The running Traefik instance has no global entrypoint http->https
redirection even though /srv/stack/docker-compose.yml declares one, so
plain http://desfoto.de/ answered with Traefik's default 404 once the old
desfoto-redirect-http router was removed. Route desfoto.de through its own
http router (desfoto-http + desfoto-http-to-https, permanent redirect) via
the proven live Docker provider instead of restarting the shared proxy.
Document the live-config drift in docs/deployment.md.
