fix: compact convergence block, cache icon tooltip, Résumé IA dark theme

- Bloc FOND./MARCHÉ/Signaux seuls : 3 colonnes larges → 1 ligne compacte
- cache 2h : retiré de l'affichage inline → icône Database tooltip (hover)
- Résumé IA : text-indigo-600 → text-slate-400/hover:slate-200 (harmonisé)
- Modal Résumé IA : bg-white → dark (bg-slate-900, textes slate-200/300)
- Dot "Réel" → abbr "Tx.R" + tooltip explicatif (Taux Réel = CT − CPI YoY)
