Put "workflow" on Dashboard edit links when they're disabled

Summary:
Depends on D20367. Ref T13272. When an edit action is disabled, we add "workflow" so that the "You can't do this" message renders in a dialog instead of a separate page.

These actions are implemented in a nonstandard way; standardize them.

Test Plan: Clicked both actions as a user who could take them (got normal behavior); and as a user who could not (got permissions dialog errors).
