Two related fixes around the order/invoice number:
1) The thank-you page and the customer-account order page were showing
the bare Shopify order name (e.g. '#1034') as the payment reference,
while the PDF (and its GiroCode QR) used the canonical invoice
number (e.g. 'RE-1034'). Banks treat each unique reference as a
separate payment, and several reject the '#' character outright \u2014
so customers who pasted the thank-you reference into their banking
app ended up with a payment the shop couldn't reconcile.
New shared helper resolveOrderRemittance() (services/invoice/
remittance.server.ts) returns the single source of truth for the
reference: latest non-cancelled Invoice row for the order, falling
back to '${prefix}${orderNumber}' when no PDF has been generated yet.
Both /api/public/payment-info and /api/public/girocode.png now route
through it, so the thank-you page, the customer-account page and the
GiroCode QR are guaranteed to match the PDF byte-for-byte.
2) Drop the redundant '\u00b7 Bestellnummer: #1004' suffix from the PDF
title when the invoice number's trailing digits already match the
Shopify order name (default 'order_number' numbering mode). In that
mode the two strings carry identical numeric content and the suffix
only adds noise; sequential mode (RE-7 vs #1004) keeps the suffix.
- New smoke assertion verifies the suppression triggers on
invoiceNumber='RE-1004' + orderName='#1004' and that the invoice
number itself is still shown.
- Both endpoints now also query 'Order.number' (already covered by
read_orders) so the fallback path can build the prefix+order-number
string without requiring the Invoice row.
