feat: implement SummaryView with Clinical Alert (Task 6)

- Create SummaryView component with clinical alert banner
- Clinical alert: amber background, warning icon, acknowledge interaction
- Alert animates in with spring effect, dismisses with checkmark → collapse
- Demographics card: full width, two-column key-value layout
- Active Problems card: 3 active/in-progress items with traffic lights
- Current Medications Quick View: 4-column table showing top 5 skills
- Last Consultation card: preview of most recent role
- Add navigation handlers for view switching
- Respects prefers-reduced-motion for all animations
- Proper table semantics and accessibility attributes
