[IMP] stock_picking_batch_custom: add full-screen operator view for batch picking

Add a "Vista Operarios" button in the batch form header (visible when
in_progress) that opens a full-screen list of stock.move.line filtered
by the current batch. The view shows only the fields operators need
(category, product, partner, home_delivery, consumer_group, collected,
quantity) with larger rows and touch-friendly quantity input via CSS.
