feat: F011 match card system

- MatchCardViewModel: typed view model decoupling card from raw API data
- Sub-components: MatchCardHeader, MatchScoreDisplay, MatchReasonList, TradeoffList, MatchDataQualitySummary, MatchActionToolbar, MatchCardSkeleton, MatchCardRestrictedState
- 4 variants: MatchCardCompact, MatchCardExpanded, MatchCardReview, MatchCardCompareMini
- MatchCard: main entry point with variant prop
- matchCardAdapter: buildMatchCardViewModel() converts UnifiedMatchResult -> ViewModel
- UnifiedResultCard: now thin wrapper using MatchCardCompact via adapter
- FUTURE_AVAILABILITY always shows non-dismissable disclaimer
