package.stop/restart on orchestrator-managed stacks (immich, indeedhub,
btcpay, netbird, mempool) addressed live CONTAINER names; unknown app ids
fell through to raw podman stop/start, racing systemd's --rm cleanup of the
quadlet unit — the container vanished on stop and the start half found
nothing (immich RESTART FAIL + indeedhub stuck restarting, gate 2026-07-09).
Now stack ops resolve member APP ids (reverse start order for stop) so the
orchestrator drives the quadlet .service; user-stop markers are written for
member app ids too (covers absent containers), and the orchestrator stop
fan-out treats an already-missing container as stopped.
