Fetch Meta's preview URL for a flow.

GET

https://api.sudonum.com.com/v2/whatsapp/flows/{uuid}/preview/

Asks Meta for a web preview of the flow and returns the URL it hands back. The URL is short-lived and issued per request -- fetch it when you are about to open the preview rather than caching it.
This is the one route that calls Meta synchronously, so it is also the one that fails when Meta does. A flow that has not been created on Meta yet (empty flow_identifier) is a 400 without any call being made.
Requires the whatsapp.view_flow permission.
