- Produktformular: Auswahl aller verwalteten Einheiten passender Art (plus Packungen), inkl. Umrechnung beim Wechsel. - Die gewaehlte Erfassungseinheit wird gespeichert (products.min_stock_unit_id / min_stock_in_packages) und exakt so wieder angezeigt - vorher wurde sie aus der Produkteinheit abgeleitet. - ProductOut liefert min_stock_display + min_stock_unit_label; Produkttabelle zeigt den Mindestbestand damit in der erfassten Einheit mit Einheit dahinter. - Migration: ADD COLUMN IF NOT EXISTS fuer die zwei neuen Spalten.
