Make "Create Document" in Phriction use workflow

Summary:
My claims that this worked on D4183 were incorrect:

  - Make it work.
  - Then use it.
  - Also make cancel URI not cancel to the same page.

Test Plan: Clicked "Create Document", got a workflow on-page dialog instead of a page transition.
