feat: onglet Marchés + TvMiniChart sans popup + cache RP 48h + OIS default

- page.tsx: onglet '🌍 Marchés' — S&P 500, VIX, DXY, Or (TvMiniChart 2x2)
- TvChart: prop dateRange configurable sur TvMiniChart (défaut 1M)
- ReportTab: TvAdvancedChart → TvMiniChart (plus de popup TV), Or remplace US10Y
  S&P 500/VIX dateRange=12M (daily), DXY/Or dateRange=60M (weekly)
- rateprobability: cache TTL 4h → 48h (OIS revient même sans GitHub Actions hourly)
