UX decision (carnet #78): the human UI of IdeA is French by default,
uniform per surface — proper nouns and technical acronyms (URL, LAN,
IP/CIDR, HTTPS, API, CLI…) stay as-is. Settings mixed English (AI
Profiles, Deployment) with French (Appareils, frozen by UX for #77).
Renames the Settings menu/nav, the Profils IA and Déploiement panels
(titles, actions, states, help text) to French, per the carnet's
exhaustive list. Updates the affected tests accordingly.
