The StripeInvoiceService was only creating line items for tickets but missing
the 1€ service fee, causing a discrepancy where customers paid 26€ via Stripe
checkout but the generated invoice only showed 25€.
- Add service fee line item to Stripe invoices in StripeInvoiceService
- Update all related tests to expect two line items (tickets + service fee)
- Fix order controller test to account for service fee in total calculation
Now Stripe invoices properly match the amount paid: tickets + 1€ service fee.
