When the backend was down the cabinet got stuck on a blank loader: the bootstrap token refresh used bare axios with no timeout (hung forever), and every interceptor guard required an HTTP response — so a transport-level failure had zero handling and no error UI ever appeared. Add a full-screen ServiceUnavailableScreen (extends the existing blocking-store pattern) shown whenever the backend is unreachable, that auto-recovers when it returns: - New 'backend_unavailable' blocking type + BlockingOverlay branch; mirrors MaintenanceScreen, CloudWarningIcon, i18n in ru/en/zh/fa. - api/health.ts: pingBackend() probes the root /health/unified (bypasses the /api baseURL + interceptor); URL derived from the origin for remote/sub-path deploys; 502/503/504 count as down. reportPossibleBackendDown() confirms an outage with a liveness probe before flipping, so a one-off blip never blanks a loaded app. - Detected from the response interceptor (no-response) and the bootstrap refresh path; doRefresh gets a timeout so it can no longer hang. - A transport failure during refresh now PRESERVES the session (distinguished from a rejected token via lastFailureWasTransport) instead of logging the user out, so recovery actually resumes. - Recovery lifts the overlay + refetches for an already-loaded session, and only hard-reloads when the initial bootstrap never reached the backend — no lost form state. Manual retry + 5s auto-poll. Dev proxy for /health.
