v0.1.32 — Bulk-Offboarding aus dem Geraete-Tab, Geraete-Ladefehler behoben

- Bulk-Offboarding aus dem Geraete-Tab (Checkboxen + Alle, POST /api/offboard/resolve)
- Fix "Geraete konnten nicht geladen werden" (400): managementState raus dem $select,
  $orderby entfernt, Namensfilter-Fallback auf deviceName, beta-Endpoint
- Bessere Graph-Fehler-Diagnose (Graph-Body an die Meldung anhaengen)
- Offboard: Grund fuer nicht gefundene Autopilot-Zuordnung sichtbar (autopilotNote)
