Retire the park-lab stack from art-docker-station

That host is becoming a Traefik edge, and parking's prod override brings its own
Caddy on `network_mode: host` holding :80 — the two cannot share the port. The
lab tier moves to a dedicated bench PC rather than contorting either side.

This also names what has been holding :80 on that box: the edge stack deployed
there on 2026-09-01 failed with "address already in use" and the owner was
recorded as unidentified. It was almost certainly this Caddy.

REMOVING THIS BLOCK DOES NOT STOP ANYTHING. The containers keep running and keep
the port. Destroy park-lab from Komodo Core BEFORE syncing this removal:
DestroyStack names a stack and Core resolves where from its own synced copy of
the definitions, so a sync that drops the block first takes the teardown handle
with it. If that has already happened, remove the containers by hand on the host
— there is no compose project context on a Komodo-managed box.

Three Core secrets are now unreferenced: art_docker_station_jwt_secret,
art_docker_station_event_signing_key, art_docker_station_backup_key. Lab keys
with no real ledger behind them, so they are safe to delete once the stack is
gone.
