feat: milestone dots on dashboard progress bar with legend

- Progress bar now shows auto-tracked sub-deadline milestones as dots
- Passed milestones: grayed out dot + strikethrough label
- Active milestones: amber dot with descriptive label
- Each milestone has a tooltip with context-aware text (e.g.,
  "Verificare expirata — nu se mai pot solicita clarificari")
- Legend below progress bar shows all milestone labels
- Wider progress bar (w-32) to accommodate milestone dots
