Reduce code duplication in Phortune account controllers

Summary:
Ref T12451. This is a GREAT comment (A++) but we only need one copy of it.

This uses a pattern similar to Projects, which is a little weird but works well enough.

Test Plan:
  - Viewed all four tabs of an account.
  - Viewed a page with a bad account ID which 404'd properly.
