fix: globalen Mandantenfilter in Ordner-/Dokumentenbaum respektieren

Die Baumansichten (DocumentTreeView, DocumentCategoryTreeView) bauen
ihr Queryset manuell statt ueber ein NetBoxModelFilterSet, wodurch das
netbox-utilities-Plugin seinen tenant_id/tenant_group_id-Parameter nicht
injizieren konnte und ausserhalb des gewaehlten Mandanten liegende
Ordner/Dokumente mit angezeigt wurden. Liest jetzt den oeffentlichen
Scope aus netbox_utilities.tenant_scope direkt aus (fallback: kein
Filter, falls das Plugin nicht installiert ist).
