Fix 403s in Phrequent by rendering actions as forms, and make properties fancier

Summary:
Also cleans up some stuff like logged out users a bit. This provides a more subtle alternative to {D5485}.

(This is fairly rough, and the icons need to be sprited if we stick with this approach.)

Test Plan:
{F38047}
{F38048}
