Account Invoice Report Stock Packaging

This module adds packaging information to the standard invoice report. On every invoice line that is linked to stock moves with a packaging, the quantity column now also shows a small text in brackets listing each packaging and how many of it were moved, for example "3 Box, 1 Pallet".

Where it appears: - On the invoice document itself (the PDF or printed invoice generated from an invoice record), inside the invoice lines table, right after the quantity.

What it does: - For each invoice line, it looks at the related stock moves that have a packaging defined, groups them by packaging, adds up the packaging quantities, and displays the result as text. - If no packaging information is found for a line, nothing extra is shown, so invoices without packaging stay unchanged.

Which areas it touches: - It extends the accounting model account.move.line with a helper that collects the packaging details. - It modifies the standard invoice report template account.report_invoice_document. - It relies on the packaging quantities prepared by the stock_move_packaging_qty module and on the link between stock moves and invoice lines provided by stock_picking_invoice_link.

No new menus, buttons, settings or automatic actions are added; the change is purely a display addition on the invoice report.
