feat(case-ui): agents roster + awaiting-you banner; Hebraize drafts table

- Agents tab: render the AgentStatusWidget roster at the top of the activity
  feed ("who's doing what right now") and surface pending agent interactions in
  an amber "ממתין לתשובתך" banner above the timeline (mockup 18i key wins).
- Drafts tab: Hebraize the drafts-table headers File/Size/Date → קובץ/גודל/תאריך
  (mockup 18h).

All existing feed logic, mutations and interaction forms preserved.
tsc --noEmit + eslint clean.
