cmd: remove unnecessary GatedUi 

The intent of this struct was to prevent non-json output to stdout. With
the previous cleanup, this can now be done by simply changing the stdout
stream to io.Discard.

This is just one example of why passing around io.Writers for the
streams is better than the UI interface.
