Stock Picking Report Custom Description

This module links the free-text description written on a sales order line with the stock operations generated from that order, so warehouse staff see the same wording on the picking documents.

• When a stock move is created from a sales order line, the line's description is copied onto the move's manual picking description, unless it is empty or is just the product name.
• If the product name appears at the start of the description, that repeated product name is removed before copying, so the text is not duplicated.
• If someone later edits the description on the sales order line, the change is pushed to the related stock moves automatically.

The module extends sale.order.line and stock.rule and relies on the standard sale and stock flows from sale_stock. It adds no new menus, screens, buttons or reports of its own; the effect is visible on existing delivery/picking documents and their printed reports. No scheduled jobs, emails or extra validation rules are added.
