shared_catalog_product_item doesn't have unique key constraint

[davidtabat]

Please add a unique key constraint to the shared_catalog_product_item table based on sku and customer_group_id:

<constraint xsi:type="unique" referenceId="SHARED_CATALOG_PRODUCT_ITEM_CUSTOMER_GROUP_ID_SKU">
    <column name="customer_group_id"/>
    <column name="sku"/>
</constraint>

This constraint will prevent duplicate entries with the same sku and customer_group_id, which would otherwise cause the PLP to become inaccessible due to an collection error: "Item with the same ID already exists."
