Qr codes bepalen

- Prerolled joints krijgen 1 code (doosjes zijn universeel): dropdown in review app, met joints die er op dat moment op de prijslijst staan
- Losse grammen en de rest die gaan naar {shop_id}/{product_id}

Besproken:
- ook een generieke code per product type: joint, cannabis, edible, vape, resin, oil
- losse codes mogelijk voor alle producten

GUI maken die naam + type + URL laat zien van alle dingen. Met vinkje: om QR code aan/uit te zetten; zodat je makkelijk testen.

No files or tests are listed, so first inspect the codebase for where QR-code generation and assignment is implemented, and for the review app product-listing UI flow. Trace how product types and pricing-list visibility are determined, and where product URL routes are assembled with {shop_id}/{product_id}. Then check admin/front-end components that expose product actions for adding a verification UI, and validate with tests or manual run-through once a name+type+URL view with a QR enable/disable toggle is present for all items.
