Modernize most somewhat-weird Diffusion controllers

Summary: Ref T4245. This gets everything else except serving HTTP requests (complicated) and lint (quite weird).

Test Plan:
  - Viewed a diff.
  - Viewed externals.
  - Viewed history table to see last modified.
  - Did path completion and validation in Owners.
  - Did tree path search in Diffusion.
  - Viewed a repository.
  - Created a new repository.
  - Looked up symbols.
