ITA - Documento di trasporto - Collegamento con ordine di vendita/acquisto

This module connects Italian transport documents (DDT) with the sale and purchase orders they come from.

On both sale orders and purchase orders you get a new "Delivery Notes" button in the top button area of the form. It shows a counter with the number of transport documents linked to that order, and it only appears when at least one document exists. Clicking it opens the related transport documents: if there is only one, its form opens directly; if there are several, a filtered list opens; if there are none, the window simply closes.

The link is calculated automatically from the order lines: each transport document line is matched back to the sale or purchase order line it fulfils. On purchase order lines you can also see the related transport document lines and the receipt (stock picking) they belong to, and each transport document line stores the purchase order line it refers to.

No new menus are added; the feature appears inside the existing sale order and purchase order screens. It touches sale.order, purchase.order, their lines, and stock.delivery.note.line.
