Modernize more Diffusion controllers

Summary: Ref T4245. Standardize how context is read, minor updates / modernizations / consistency tweaks.

Test Plan:
  - Viewed a change.
  - Viewed brnaches.
  - Edited a commit.
  - Viewed tags.
  - Viewed history.
  - Added, edited and deleted a mirror.
  - Viewed push events.
  - Viewed a particular event.
  - Viewed ref disambiguation.
  - Viewed repository list.
  - Ran automation test.
