feat: appointment card colors by status, MassHealth badge, date nav controls

- Default card color: light (bg-slate-100 / dark text)
- Blue card when procedures selected, gray when claim has a number
- Status badge: green/red from appointment or patient-level MassHealth status
- Solid dot badge (removed ring), overflow-visible to prevent corner clipping
- Date nav: << < [today circle] > >> for week/day jumps
