// ui_repo_probe.go — NS-03 retry-probe handler. Re-dispatches an init
// job against a host so the operator can re-test creds / connectivity
// without typing the hostname (no destructive shape: restic init is
// idempotent against a populated repo, so this is safe to spam).
//
// On success the WS handler's job.finished hook flips repo_status
// back to "ready" (or "init_failed" with a fresh error message).
