NEW|New add drag-and-drop functionality for managing draft expedition lines

We keep the standard drag-and-drop workflow (ajaxrow.tpl, tdlineupdown column, /core/ajax/row.php), so the user experience matches what you get on quotes/orders/invoices.

1. Shipments have one peculiarity: a single visible line can represent several llx_expeditiondet rows (multi-warehouse/lot). We therefore override Expedition so that reordering a line updates every sub-line sharing the same fk_origin_line, and fetch_lines() now sorts by ed.rang to mirror the stored order. row.php instantiates Expedition whenever table_element_line=expeditiondet, letting the existing AJAX flow trigger these overrides without any frontend changes.

@eldy, I don't know how to fix that because it's an override and the default method doesn't have a type

@atm-corentin try to replace

@param array $rows

by

@param int[] $rows

@eldy thanks it's good now
