Adds MarketKpis domain type with formula-based radius scaling, a MarketKpiPanel component (vacancy rate, platform searches, avg vacancy duration, demand/supply ratio — color-coded with interpretation badges), and integrates it at the top of PropertyMarketSignalsTab. Demand/supply section labels now update with the selected radius. Mock data covers all 5 existing market reports. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
