Sale Purchase Procurement Group by Line

This is a technical bridge module that installs automatically when both related modules are present. It does not add any new menu, screen, button or report.

What it changes: - On a sales order, the computed number of related purchase orders now also counts purchase orders that were created through the procurement groups attached to each sales order line, not only through the sales order as a whole. - It looks at the stock moves linked to each line's procurement group, and follows the links to the purchase order lines that were created from those moves, as well as the original moves that point to a purchase line.

Why it matters to users: - When you use 'MTO Sale <-> Purchase' together with 'Sale Procurement Group by Line', each sales order line can have its own procurement group. Without this module, the purchase order count shown on the sales order could miss purchase orders generated per line. - With this module, the count is complete, so the 'Purchase Orders' smart button on the sales order reflects all related purchases.

It only touches the sale.order model and overrides the purchase order count computation and the method that collects related purchase orders. No other business rules, checks, emails or scheduled jobs are added.
