This commit adds a popup to show product information when clicking on an info button in the product card in the self order app. The popup shows the ecommerce description and the name of the product. The ecommerce description field has thus been moved from website_sale to the product module so that the pos_self_order module can use it. closes odoo/odoo#136906 Task-id: 3524272 Signed-off-by: Romain Derie (rde) <rde@odoo.com>
