Subject: [PATCH] [IMP] stock_picking_batch_custom: show product code as
 separate optional column

Add product_default_code related field to stock.move.line and
stock.picking.batch.summary.line. Show it as a hidden-by-default column
to the right of product_id in both detailed operations and product summary
views. Hide the code prefix from the product name via display_default_code
context so sorting is alphabetical.
