Picking: baskets as a grid and basket orders

What changed

• Picking: baskets in a grid with a fixed order, Take/Return always in the row, the active basket highlighted, order counter and Print sheet.
• New basket orders view: orders locked by status show a badge with the reason, packed ones cannot be selected; until the basket is taken the whole block is disabled.
• The order number links to the order card (in the grid and in the packing window).
• "Packing only" mode: no baskets grid, with a warning about open baskets.
• Baskets (admin): Take out (goods put back), Hand over to another packer, Close basket - recorded in the order history.
• Batch packing refuses orders from another packer's or an untaken basket and in a blocking status.
