Feat: Handle Checkout Refund webhooks

Adds Checkout webhook intake so the platform can process retried refund events without manual intervention.

Scenario Goal & Context

Goal: Verify incoming webhook requests, process the event payload, and prevent duplicate side effects when the same event is delivered again.

Background: Checkout can retry refund webhooks several times, and finance wants the system to process them automatically.
