Subject: [PATCH] feat: Add StockItem and SupplierOffering entities

Introduce new data model that separates stock catalog (StockItem) from
supplier-specific pricing/catalog info (SupplierOffering). StockItem
represents a Material+Length combination, while SupplierOffering links
suppliers to stock items with part numbers, descriptions, and pricing.
