feat: F010 unified result feed

Replace monolithic Results.tsx with decomposed component architecture:
- 8 new components in src/components/results/ (ResultTypeBadge, ResultConfidenceSummary, FeedEmptyState, FeedSkeleton, ResultFeedHeader, ResultFilterBar, UnifiedResultCard, UnifiedResultFeed)
- Reuses existing useUnifiedResults hook and compareStore
- FUTURE_AVAILABILITY cards always display non-dismissable disclaimer
- Filter by result type + sort by score/area/rent
