refactor: dashboard cards with clickable status counts + tab bar restored

- Dashboard cards show all 4 statuses inline: new (gold), contacted (blue),
  confirmed (green), declined (red) — big numbers with consistent status colors
- Each number+label is clickable to filter the tab by that status
- Tab bar restored below dashboard
- Removed filter chips from SearchBar (dashboard handles filtering)
- Open Day card uses cyan border (distinct from blue contacted status)
