strip docker type — site-publish is static-content only

Removes type: docker handling from action.yaml, scripts (build/deploy/utils/setup),
and templates (deployment.yaml.j2, service-docker.yaml.j2). Renamed
service-static.yaml.j2 -> service.yaml.j2.

If site.yaml has type: docker, parse_site_yaml() now dies with a clear message
pointing to action/image-build + action/image-push + action/image-deploy with
hand-authored apps-repo manifests. rainsounds.vino.network was the only docker
consumer and has already migrated.

Drops registry-password input from action.yaml (no longer needed).
