Sending Server Request from the page

Currently, we are sending the request directly from the devtools UI using fetch, which sometimes can be inaccurate when the app has some client states like cookies etc. We should forward the arguments to the app client, sending the request from the app, and forward the return value to the devtools UI to present it.

this would be really really cool, currently I can't quite use the server routes feature on devtools because I can't input cookies nor use the ones from the client. Would make for amazing DX!
