Feat: Handle Adyen Invoice webhooks

Adds Adyen webhook intake so the platform can process retried invoice 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: Adyen can retry invoice webhooks several times, and finance wants the system to process them automatically.
