Stock Picking Customer Reference

This module brings the customer reference that was entered on a sales order onto the related warehouse transfers, so warehouse staff can see it without opening the sales order.

• On the transfer form, a new "Customer Reference" field appears after the Responsible person.
• In the transfer list view, the same field is shown right after the Contact.
• In the transfer search bar, you can search by customer reference and use a "Client order reference" filter to group transfers by that value.

The value is taken automatically from the linked sales order and stored on the transfer, so it stays available for searching and grouping. It is read-only in practice because it follows the sales order.

The module only touches stock.picking and depends on sale_stock, so it works wherever transfers are created from sales orders. No new menus, buttons, reports, emails or scheduled actions are added.
