New sendPaymentSwitchedEmail() — sent instead of sendOrderConfirmationEmail() when confirmPaymentEmail.ts sees order.paymentSwitchedAt set. Resending the full order-confirmation (with its invoice re-attached) after a payment-method switch read like a brand-new purchase; this is a short, dedicated "Zahlung erhalten" confirmation instead, matching the order-status-email shape. Also bumps @einfach-produktiv/invoicing to 0.2.8, fixing a font-path bug that broke every invoice PDF render inside the Payload backend specifically.
