fix(invoice): detect pickup via DeliveryMethodType and show 'Abholort: <location>' meta row

- Use Order.fulfillmentOrders.deliveryMethod.methodType === 'PICK_UP' as the
  primary signal (Shopify Local Pickup app exposes this reliably; the
  shippingLine title is just the location name with no 'pickup' keyword).
  Keep the legacy shippingLine string heuristic as a fallback for custom
  shipping rates merchants name 'Abholung'/'Pickup'.
- Surface assignedLocation.name as pickupLocationName on the view model.
- Replace the 'Versandart: <location name>' row with 'Abholort: <location>'
  (DE) / 'Pick-up location: <location>' (EN); falls back to plain
  'Abholung'/'Pick-up' when the location name is unavailable.
