feat(crew): add a coordinator "Check status" button to the crew form

For a coordinator addressed by pubkey, the form now probes it on demand (the
same useCoordinatorHealth the Settings → Coordinator card uses) and shows
Connected / Quiet / Not seen / Unreachable. Reuses the existing socialUi
.coordinator status copy; no new keys.
