Sale product configurator widget product label

This is a glue module that ensures the product label and note widget works correctly when the sale product configurator is installed. It does not add new menus or models; instead, it changes how the product field behaves on the sale order form.

On the sale order form, the order lines list now uses a special widget for the product column. This widget lets users type a product name and also add a free-text label or note directly in the same field. When a product is selected, the label can be shown or hidden with a button next to the product field.

The module also patches the JavaScript component that handles the product field in sale order lines. It tracks whether the product name is visible inside the label text, and it updates the label when the user types. If the product name is part of the label, it can be removed or re-added automatically.

This module is automatically installed when both the product label widget and the sale product configurator modules are present. It only affects the sale order form view and the product field component in the backend. No new reports, emails, or scheduled actions are added.
