+Pick items record a single packaging type per row: set `is_carton` to `true` when counting
+cartons (using the product's `bulk_name`) or `false` for single units (using `unit_type`). If
+both units and cartons are needed for the same product, store them as two PickItem records so
+quantities remain distinct.
