Purchase Quick Discount

This module is a small bridge between the quick purchase screen and the purchase discount feature. It does not create new menus; instead it adds one column to the product list used when quickly building a purchase order.

What users see: - In the quick purchase product list, a new "Discount" column appears next to the supplier price. - The column is hidden when the discount is zero, so only products with an actual discount are highlighted.

The value shown is calculated automatically for each product: - Odoo looks at the vendor selected on the purchase order and the quantity being processed. - It finds the matching supplier price line for that vendor and quantity. - It copies the discount percentage defined on that supplier line into the column. - If no matching supplier line is found, the discount stays at zero.

The calculation refreshes when supplier information or the quantity to process changes, so the displayed discount stays in line with the vendor and quantity chosen.

Under the hood it touches the product.product model and the supplier information (seller_ids), and it extends the existing quick purchase product tree view. No new reports, emails, or scheduled actions are added.
