OAuth Server -- add controllers to RUD client authorizations and CRUD clients

Summary:
beyond the title, this diff tweaks the test console to have a bit more
functionality. also makes a small change to CSS for AphrontFormControlMarkup,
which IMO fixes a display issue on
https://secure.phabricator.com/settings/page/profile/ where the Profile URI is
all up in the air and whatnot

I think this is missing pagination. I am getting tired of the size though and
will add later. See T905.

Test Plan:
viewed, updated and deleted client authorizations. viewed, created,
updated and deleted clients
