Warenwirtschaft: AP-21 INCI-Erweiterungen

- Lagerort-Stammdaten Raum/Regal/Fach (storage_rooms/shelves/slots) mit CRUD
  auf Einstellungen -> Allgemein (SettingCrudController-Kinder, ein gemeinsamer
  StoreStorageSegmentRequest, generische Partials setting-list-card/-segment-form)
- Ingredient: alt_name (Handelsname), Lagerort-FKs + storageLabel(),
  scopeUsedInActiveRecipes()
- INCI-Formular: Lieferanten-Repeater mit Shop-URL je Lieferant (leer = Mail),
  Alternativname, drei Lagerort-Dropdowns
- INCI-Liste: Filter "nur aktive (in Rezeptur aktiver Produkte)" + Spalte
  Alternativer Name
- Rohstoffbestand-Detail: Bestellweg pro INCI-Lieferant (Pivot-URL statt
  order_method-Fallback), Kopf zeigt Alternativname + Lagerort
- Hinweise-Doku fortgeschrieben inkl. Chargen-Format-Entscheid ttmmjj (AP-24)

Tests: StorageSettingsTest, IngredientActiveRecipeFilterTest,
IngredientOrderFieldsTest (Repeater-Format), RawMaterialStockTest erweitert
(volle Suite 170 gruen, 613 Assertions)
