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.
