The status-pages blueprint (public + management routes) and its service move into
serverkit-status; the StatusPage/StatusComponent models stay core (G2). Core's
WordPress health-check job syncs status components only when the extension is
installed (no crash on a lean panel). Re-homes the status-page mutation authz
