Receive and validate Event Webhook Loopback (RCV) for testing integrations

Receives a webhook event payload, validates its JSON schema and signature, simulates a configurable delay, and can return custom HTTP responses for testing webhook integrations.This endpoint is intended for use in integration and end-to-end testing scenarios where webhook consumers need to validate their handling of event payloads, delays, and custom responses.<br> The endpoint performs the following: <br>· Validates the incoming JSON payload against the expected schema for <c>EventWebHookPocRequest</c>.<br>· Validates the x-gd-signature header if present, using the program-specific signing key.<br>· Simulates a configurable delay if set via the configuration endpoint.<br>· Returns a custom HTTP response if configured, otherwise returns a standard response with event identifiers.<br>
