iOS: Lagerort-Picker zeigen den vollen Pfad statt nur den Namen

Wie im Web: alle Lagerort-Auswahlen (Einlagern, Einzelstueck/Item, Objekt-Bestand hinzufuegen/umlagern/entfernen, Mindestbestand je Ort) zeigen 'Hedingen -> Keller -> Schublade 1' statt nur 'Schublade 1', damit gleichnamige Orte unterscheidbar sind. Neuer Helfer StorageLocation.path(in:) bzw. locationPath(_:in:) in Models.swift.
