feat(scheduling): rename 通知→干预, allow drill-in on intervened items

- Globally rename user-facing 通知 → 干预 (list badge, detail button, batch
  modal, CSV header, server response messages, db table comment)
- 已干预 row in detail is now clickable — opens SwapPreview which shows
  a read-only summary plus a 取消干预 action (PATCH notify /:id with
  status=cancelled). Sending is blocked while already intervened.
- Selected suggestion now follows the latest data snapshot so status
  changes from within the detail flow propagate immediately.
