The backend now answers 503 with code MAINTENANCE_MODE while maintenance is
on. Without this change a visitor got a red error toast over a broken page
client-side, and a silently empty page server-side, because fetchReq discards
the status and returns null on any failure.
- lib/maintenance.js detects the state by BOTH status 503 and the error code;
a bare 503 can come from a reverse proxy and is not maintenance
- The axios interceptor checks it before the 401 branch, so a maintenance
response never triggers the refresh-token path or logs the user out
- fetchReq redirects to /maintenance, with a silentMaintenance opt-out used by
getStateInfo: that one runs inside generateMetadata and while rendering the
maintenance page itself, where a redirect is either ineffective or loops
- redirect() works by throwing, so the try/catch blocks in the doctors,
clinics and specialties pages now rethrow NEXT_REDIRECT instead of
swallowing it
- clinicApi.js handles 503 too; it previously rendered maintenance as a clinic
with zero doctors
- The page reuses the existing 404 design and is marked noindex
