- main.tsx: on vite:preloadError (stale index.html referencing removed
hashed chunks after a redeploy) reload the page immediately.
- New ErrorBoundary around the whole router: render errors show a Persian
fallback with «تلاش مجدد» instead of wiping the DOM.
- nginx: index.html served with Cache-Control no-cache,no-store,
must-revalidate (verified live); /assets/* stays public, immutable.
After the api container restarts it gets a new IP; nginx cached the old one
at startup and kept proxying /api/* to the stale address — which by then
belonged to another service (casdoor), so login returned Casdoor's error
envelope and the frontend crashed with "Cannot read properties of null
(reading 'user')". proxy_pass now uses a variable + resolver 127.0.0.11 so
the upstream re-resolves per request. Verified: login works, and still works
after restarting the api container.
