The schedule pause/resume button (added in PR #2053) was missing from
the dashboard.md SCH3DUL3S tab docs. The action column listed only three
actions (fire-now, edit, cancel); the pause/resume toggle was undocumented.
Add the full action-column breakdown with the pause/resume semantics:
- paused rows show a 'paused' badge in the next column
- sorted middle bucket (after active, before cancelled)
- fire-now button is disabled while paused
- routes to /api/schedules/{id}/pause or /resume
