Introduces a global Products catalog plus per-family overrides and
private FamilyProducts, exposed via /api/products with a merged
search. Shopping list items and recipe ingredients gain optional
ProductId/FamilyProductId links, and a new ProductStoreSection
table remembers which section a product was last placed in at a
given store so future adds auto-assign the right section.
Frontend gets a reusable ProductTypeahead component, wired into
list-item add and recipe ingredient entry with free-form fallback.
A startup CatalogSeeder loads ~115 curated staples from an embedded
JSON resource via INSERT ... ON CONFLICT DO NOTHING; skipped under
the Testing environment so integration tests keep a clean slate.
