Manually Resend Webhooks#25

It would be nice to be able to resend (or cancel) a failed webhook attempt manually, rather than waiting for the automatic retry.

As a workaround for now, this is my flow:

1. Use the Webhook History API endpoint (Management) to get the raw payload, since the payload isn’t easily copyable from the dashboard (would be a nice add too!)
2. Locally (on my own machine), set my environment to point to prod (environment variables) and termporarily disable the code that verifies the webhook signature
3. Send the webhook payload in Postman

Note that this flow works only because I’m also checking for idempotency to avoid making dual fulfillements when PayNow eventually retries automatically after I’ve already handled this manually.
