[FIX] point_of_sale: exclude internal reference in loaded products

Previously, products loaded from the background included the internal
reference in their displayed name. This behavior was due to the
'display_default_code' context, which prevents the inclusion of
'default_code' in the product name, not being utilized within the
'get_pos_ui_product_product_by_params' function.
