Activates the per-box loop landed in the prior commit. SO External reads line.product_uom_qty; Job External reads job.qty. Inner template now renders one sticker per physical box, marking each with "X / N" in the Qty row. Verified on fp.job 2635 (qty temporarily set to 3): 3-page PDF with Qty rows "1 / 3", "2 / 3", "3 / 3" — each page identical otherwise (same WO#, same QR, same body fields).
