docker.yml (5-image matrix) and flatpak.yml (full flatpak-builder) couple the
docs + flatpak-server deploys to heavy builds. This adds a dispatchable,
build-free deploy-services.yml that just (re)places the compose files and pulls
the already-published images, so unom/infra's deploy-all can bring a fresh
unom-1 fully up in one dispatch. The flatpak ./site OSTree content is restored
from the unom-1 backup or regenerated by flatpak.yml's next publish.
