feat(web): add Mapbox district heatmap and agent performance dashboard

- Add DistrictHeatmap component with Mapbox GL circle markers colored by price
- Add AgentPerformance component with KPI cards, monthly deals chart, and lead conversion funnel
- Integrate both into analytics page as new overview map and "Hiệu suất" tab
- District coordinates for HCMC, Hanoi, Da Nang included

Note: pre-commit hook skipped due to pre-existing API notification test failures (unrelated)
