marcoandClaude Opus 4.8 7bfcfc18ad Policies: Bulk-Zuweisung von Gruppen inkl. Alle Geräte/Alle Benutzer 
- Neuer Toolbar-Button "Gruppen zuweisen" im Policy-Tab: mehreren
  ausgewählten Policies (typübergreifend) in einem Schritt dieselben
  Include-/Exclude-Gruppen zuweisen.
- Zwei Modi: "Hinzufügen" (bestehende Zuweisungen werden gelesen und
  gemergt, da Graph /assign Full-Replace ist) und "Ersetzen".
- Integrierte Include-Ziele "Alle Geräte" (allDevicesAssignmentTarget)
  und "Alle Benutzer" (allLicensedUsersAssignmentTarget), dedupliziert
  und mit Exclude-Gruppen kombinierbar.
- Invoke-PolicyAssignEndpoint um mode/allDevices/allUsers erweitert.
