[Feature Request]: Test and validate rules before deploying

The UI to create rules looks eerily similar to the way you create dynamic groups in Microsoft Entra, which is great.

One thing that is missing however, is that unlike in Entra, there is a way to validate your rule before adding it. Entra allows you add users to validate if the user would be part of the group matching the rule or not.

It would be great if CF offered the same feature when creating rules. A way to add sample urls and see if it would match the rule or not. This would be great rather than deploying something and then testing in prod or a different account.

I think Trace https://developers.cloudflare.com/fundamentals/basic-tasks/trace-request/ might be a close solution to this.
