Receive a provider webhook

Ingestion endpoint called by the payment provider (e.g. MercadoPago) when a payment event occurs. Payssage verifies the provider signature, normalizes the event, stores it, and dispatches deliveries to every webhook endpoint on the event's wallet. Returns 200 even for expected-and-ignored cases (unknown event types, duplicate deliveries) so the provider does not retry; bad signatures return an error. Public — providers cannot send an Authorization header.
