Purpose:
In orders app, when linking a POL to an inventory instance, all product IDs should be transferred - exactly as it happens when a users changes the "Change instance connection" function.

Current behaviour: If you link a POL to an Inventory instance (via title look-up), only a few product IDs are transferred: usually ISBN, ISSN and ZDB-ID. Problem: It is difficult to search in the Orders and Inventory apps if you do not know 100% which IDs are searchable.
Align the link instance transfer of product IDs with the "Change instance connection" feature that brings ALL product IDs. Need to be mindful that this does not cause matching issues with data import before working on implementation.
User story statement(s):

As an acquisitions librarian
I want all product identifiers from an instance brought into orders on linking
so that functionality aligns with change instance connection

Scenarios:

1. Scenario: Import all product identifiers when purchase order line is linked

   • Given a user is creating a Purchase order line

   • When the purchase order line is linked to an inventory instance

   • Then all product identifiers should be brought into the purchase order line item details
