Increases the delay before Swarm restarts a failed uptime-kuma task from the default 5s to 30s. Applied live via `docker service update --restart-delay 30s` on 2026-07-26; this persists it so it survives the next stack deploy. Note: this does not pin the task to a specific node or prevent cross-node reschedule races against the CephFS-backed SQLite data dir - it only slows the restart-after-failure loop. See prior incident notes for the DB corruption root cause discussion.
