chore: supprime les derniers restes de l'IA dans les Paramètres

La section « IA Copilot — OpenRouter » annonçait « pour les analyses de
gammes », mais aucun code ne consommait cette clé : elle était décorative.
Supprimée, ainsi que les routes devenues orphelines /api/admin/ai-config,
/api/google-ai/models et /api/openrouter/models.

Nettoyage de l'état correspondant dans la page : clé, liste de modèles,
fournisseur d'IA et modèle Google ne faisaient plus qu'un aller-retour entre le
chargement et l'enregistrement, sans aucune interface pour les modifier.
handleSave n'enregistre donc plus que l'URL de la base.

La règle set-state-in-effect s'est mise à signaler le `setIsMounted` du montage,
inchangé mais devenu analysable une fois le code IA retiré : dérogation locale,
comme dans api-connection-info.tsx, puisque poser l'indicateur au montage est
précisément ce qui évite l'écart d'hydratation.
