refactor: Nettoyage complet du fichier config.json

- Suppression des sections obsolètes (agents, centres, CTI, preferences)
- Conservation uniquement de la configuration SignalR nécessaire
- Les agents et centres sont maintenant gérés côté serveur via SignalR
- Réduction du fichier de 118 lignes à 8 lignes (93% de réduction)
- terminalsSimulation conservé comme fallback pour le mode dégradé
- Mise à jour du changelog pour documenter ce nettoyage
