fix: resolve all TypeScript errors and refactor oversized components

- Fix MUI v9 API: PaperProps/InputLabelProps/inputProps → slotProps in 6 components
- Add ExternalMarketResult alias, PropertyUnit import, OPERATIONS workspace config
- Fix TradeOff.description → .concern, ScoreFactor.label → .criterion
- Make schattenmarktRelease.leadTimeMonths optional, fix mock-data enum values
- Fix useMatchDetailData query typing, weightingService missing WeightProfile keys
- Split Pipeline/Compare/MatchDetail/IntelligenceMatchCard into sub-components
- Fix all test fixtures (CreateNeedInput, CreatePropertyInput, TradeOffInput, etc.)
- Add vercel.json for deployment, zero tsc errors
