feat: timeline milestones for deadlines, auto-close reply entries, cleanup

- Entry created via "Inchide" flow now gets status "inchis" with closureInfo
- New DeadlineTimeline component: main deadlines as cards with progress bar,
  auto-tracked sub-deadlines as milestone dots on horizontal timeline
- Auto-tracked deadlines hidden from dashboard when user deadlines exist
- Verification milestone shows "Expirat — nu se mai pot solicita clarificari"
- Parent closureInfo now includes linkedEntryId/Number of the closing act
- Removed orphaned deadline-table.tsx and use-deadline-filters.ts
