fix: rescan first before gateway restart when backend 404

- frontend now tries GET /api/dashboard/plugins/rescan via SDK first (reloads gateway+dashboard plugins without _HERMES_GATEWAY bug), waits 3s and re-checks status
- only if still 404 then falls back to POST /api/gateway/restart
- ensures new code (systemd/nohup + ntfy) loads without needing manual dashboard restart
- bump v2.5.3
