Warenwirtschaft: AP-51 — Lagerplatz-Felder für Produkte & Verpackung

Lagerplatz-Zuordnung (Raum/Regal/Fach) gab es bisher nur bei Rohstoffen. Jetzt
dieselbe Storage-Hierarchie (StorageRoom/Shelf/Slot) auch für Produkte und
Verpackungsartikel, inkl. Anzeige an den passenden Stellen.

- Migration: storage_room_id/shelf/slot an products + packaging_items
  (nullable, FK constrained, nullOnDelete).
- Models Product + PackagingItem: fillable + storageRoom/Shelf/Slot-Relationen +
  storageLabel() („Raum 1 | Regal 3 | A").
- Produktformular (Inventar-Abschnitt) + Verpackungsformular: Auswahl-Zeile
  Raum/Regal/Fach; Optionen kommen aktiv/sortiert aus den zentral pflegbaren
  Bausteinen (Einstellungen → Allgemein).
- Speichern: ProductRepository normalisiert leere Auswahl -> null (FK);
  PackagingItem-Requests + Repository um die drei Felder erweitert.
- Anzeige: Produktbestand (Sub-Zeile mit Marker), Produktverpackung-Übersicht
  (neue Spalte „Lagerplatz").
- DeletionGuard: Lagerbaustein ist nicht löschbar, solange Produkte/Verpackung
  darauf verweisen (analog Rohstoffe).

Tests: 4 neue (Produkt speichern + leer->null, Verpackung speichern + Anzeige,
Löschsperre, freier Baustein löschbar). Migration auf Dev-/Live-DB gelaufen.
Suite 331 grün.
