Conduit -- kill tabs

Summary:
this has a single side nav now. added a Utilites section below the methods
which houses Logs and Token.

On logs I ended up deleting this whole concept of "view" and the existing side
nav -- I think there were plans to add a way to filter down to subset of the
conduit calls. For logs, I envision that being a separate first class tool when
/ if we think we need additional complexity.

On token I made the form FULL so it was like the rest of the views in this page.

Test Plan:
looks good! clicked on a few methods and it worked! clicked on the
logs and they were there! clicked on the pager within the logs and it worked!
checked out the token page and it looked good too.
