Webhook replay tool

Generate replayable cURL commands for payment webhooks.

Paste or generate a fake payload, choose a provider, and copy a local replay command with the right signature header. Useful for testing raw-body parsing, duplicate delivery behavior, and CI fixtures before checkout goes live.
