feat: connect Top 3 Metrics to real data from Supabase and macro scans

- add /api/portfolios/{id}/summary endpoint to backend
- parse Sharpe and Drawdown from latest portfolio snapshots
- parse Market Regime from macro_scan/scan_summary.json
- update MetricHeader to fetch real-time metrics with polling
- pass portfolio_id to dashboard and trigger methods
