Move QR codes to admin page

The old admin interface showed QR codes

Should be moved to pricelist GUI

Start by locating the templates/components for the old admin page where QR codes are currently rendered and the corresponding pricelist GUI screen. Then trace the route or controller wiring for both views to identify where the QR block should be moved safely. No tests are named; validate with a local run or UI check that QR codes appear on the pricelist page and are removed from the old admin page.
