Convert OAuthServer to Transactions + EditEngine

Summary: Ref T7303. This application is currently stone-age tech (no transactions, hard "delete" action). Bring it up to modern specs.

Test Plan:
  - Created and edited an OAuth application.
  - Viewed transaction record.
  - Tried to create something with no name, invalid redirect URI, etc. Was gently rebuffed with detailed explanatory errors.
