Allow OAuth applications to be disabled instead of destroyed

Summary: Ref T7303. This interaction is very oldschool; modernize it to enable/disable instead of "nuke from orbit".

Test Plan:
- Enabled applications.
- Disabled applications.
- Viewed applications in list view.
- Generated new tokens.
- Tried to use a token from a disabled application (got rebuffed).
- Tried to use a token from an enabled application (worked fine).
