Allow workboards to be disabled, hiding "(Backlog)" column annotations

Summary:
Fixes T7410.

  - Adds a "Disable Workboard" action to the "Manage Backlog" menu.
  - We'll probably move this somewhere else if/when that column gets too messy.
  - Disabling a board hides it, prevents it from being recreated by non-editors, and hides the "Project (Backlog)" annotations.
  - Resotring a board puts it back in pristine condition.

Test Plan:
  - Disabled a board.
  - Verified "(Backlog)" annotations vanished.
  - Enabled a board.
