Lieferanten-/IT-Service-Cockpit direkt auf der Asset-Seite öffnen

Statt beim Klick auf ein Lieferanten-/IT-Service-Asset zur Lieferanten-Seite zu
wechseln, wird das Fach-Cockpit jetzt als Popup auf /assets gerendert; Schließen,
Bearbeiten, Speichern und Löschen bleiben auf der Asset-Seite.

- backHref-Prop an SupplierDetail/Edit- und ServiceDetail/Edit-Modal: alle
  Schließen-/Bearbeiten-/Abbrechen-Links leiten sich davon ab (Default /suppliers)
- withQuery-Helper (lib/supplier) für korrekte ?/&-Verkettung
- updateSupplier/updateService lesen returnTo (verstecktes Feld) und leiten dorthin
  zurück; deleteSupplier/deleteService bekommen returnTo-Parameter
- Kind-Actions revalidieren zusätzlich /assets, damit das Popup dort aktuell bleibt
- SUPPLIER_INCLUDE/SERVICE_INCLUDE in lib/supplier-include ausgelagert und von
  beiden Seiten genutzt
- assets/page.tsx bestimmt die Popup-Art vorab (supplier/service/asset) und rendert
  das passende Cockpit mit backHref="/assets"; profillose Alt-Assets bleiben Assets
