Task 10: Build LatestResults tile

- Created LatestResultsTile with 2x2 metric grid displaying four KPIs
- Each MetricCard shows value (22px, colored by variant), label, and sub text
- Metric cards use 6px radius, border-light, dashboard background
- Data sourced from src/data/kpis.ts (Budget £220M, Savings £14.6M, Years 9+, Team 12)
- CardHeader with teal dot + "LATEST RESULTS" + "Updated May 2025" right text
- Added data-kpi-id attributes for Task 17 flip card interaction
- Wired into DashboardLayout as half-width tile (left column)
