refactor(store): extract shopping methods from sqlite.go into shopping.go

Pure move: UserShoppingItem type, its CRUD methods, and
SetShoppingItemChecked/GetShoppingItemChecks, plus their tests and
setupTestStoreWithShopping helper, out of sqlite.go. No behavior
change. Mirrors the existing internal/handlers/shopping.go naming.
