New events — payment.refunded and payment.partially_refunded

Two payment webhooks are now available so your invoicing system can issue its credit notes: payment.refunded fires when a refund completes the refund of a payment, and payment.partially_refunded when a refund covers only part of it. Both carry the original payment in data plus a new data.refund block (idRefund, amount, lines, date). Every envelope now also includes version.

See the Payment refunded and Payment partially refunded references for the full payload.
