Sale Order Line Stock Moves History

This module makes stock movement history visible directly from a sales order. On the Sales Order form, inside the order lines list, a small history icon button appears next to the delivered quantity of each line.

Clicking that button opens a read-only list titled "Stock Moves History for <product>" showing the stock move lines related to that specific sale order line and product. The list shows the product, date, reference, source and destination locations, quantity, unit of measure, status and who completed the move.

Business rules visible in the screen: - Quantities going out of internal or transit locations are highlighted in red; quantities coming into internal or transit locations are highlighted in green. - The status badge is colour-coded: cancelled in red, assigned in blue, draft in grey, done in green, and other statuses in orange. - The list is read-only: no new stock moves can be created from it.

It touches the sales order line model (sale.order.line) by adding the button action, and reuses the stock move line model (stock.move.line) for the history list. No new menus, scheduled jobs or emails are added.
