fix: Résumé IA inline color, tooltip Implied Pts custom renderer, tryUrl cancel

- NarrativeButton: style inline pour forcer #94a3b8 (imbattable vs bundle CDN caché)
- CurrencyCard: Tooltip Implied Pts remplacé par custom content renderer (text visible)
- investinglive.ts: res.body.cancel() en fire-and-forget (ne masque plus le succès)
  + console.log article courant/précédent pour diagnostic dans logs Vercel
