✅ GroupController (index, create, store, edit, update, destroy)
✅ GroupPolicy (viewAny, view, create, update, delete)
✅ Маршруты: /admin/organizations/{organization}/groups (shallow resource)
✅ Blade-шаблоны:
  - admin/groups/index.blade.php (список групп организации)
  - admin/groups/create.blade.php (форма создания)
  - admin/groups/edit.blade.php (форма редактирования)
✅ Обновлён admin/organizations/show.blade.php (управление группами)
