deployer.py status lookup used f"{decky.name}-{svc}" verbatim, so
docker_api (underscore) resolved to "decky-devops-docker_api" while the
actual container is named "decky-devops-docker-api" (hyphen). Status
would always report it absent/degraded even when running.
Fix: normalize underscores to hyphens in the container name lookup,
consistent with how all service plugins name their containers.
