feat(portal): add StatusBadge to appointment cards

Add a StatusBadge component that renders human-readable labels
(Confirmed, Pending, Waitlisted, etc.) with semantic color classes
for appointment cards in the portal. Replaces raw status strings.

- Added STATUS_LABELS map for human-readable status labels
- Updated STATUS_COLORS to use accessible amber/blue tones
- Exported StatusBadge for testing
- Added unit tests for all 7 badge states plus fallback
- Updated UAT_PLAYBOOK.md §5.12c with status badge test cases
