Add bulk import detection on add missing product

When a user is inventoring some items (aka a computer), often products for certain items are missing. This is already shown to the user by the banner "Item has no product" with the button "Create it now". Often though the item has been created with bulk import and along with it the products are partially filled in. When a user uses the "Create it now" button, a check should be done whether a product in bulk exists and offer the option to the user to start from that rather than from "clean". Probably fuzzy search should be done.
