feat: implement Phase 2 (component library) + Phase 3 (dashboard)
Phase 2 - New shared components:
- Button: filled/outlined/text/icon variants, loading state
- StatusChip: colored badge with icon per status (completed/running/pending/failed)
- StatCard: icon circle with tinted bg, big number display
- EmptyState: centered icon, title, description, optional action
- SkeletonCard: shimmer loading placeholders (stat, list item, table row)
- SegmentedButton: active shows Check icon, secondary-container colors
- AirportChip: PlaneTakeoff icon, error hover on remove
- Toast: updated to Lucide icons + design token colors
Phase 3 - Dashboard redesign:
- 5 stat cards with skeleton loading
- Status chip separated from destination text (fixes "BDS→DUScompleted" bug)
- Hover lift effect on scan cards
- Relative timestamps (Just now, Xm ago, Today, Yesterday, N days ago)
- EmptyState when no scans exist
