Product Add-Ons for WooCommerce

Add an option to display add-on prices in the item meta of the order details screen (Orders > Edit Orders). This feature should function similarly to older versions of the Product Add-Ons extension, which showed a _pao_total custom meta value.

Currently, add-on prices are visible during product configuration when creating manual orders, but they do not appear in the order details after a product is added. This improvement will enhance the usability of the order screen, especially for handling and viewing paid orders.
