feat: finalise multi-profil Codex/Claude avec catalogue de modèles

- Backend : clone_profile_from_seed généralisé (non OpenCode)
- Backend : catalogue static Claude/Codex (3 modèles chacun, 1 recommandé)
- Backend : commandes Tauri list_claude_models/list_codex_models
- Frontend : ProfilesSettings refonte en onglets Codex/Claude + create/duplicate/edit/delete
- Frontend : ModelSelect searchable partagé + fallback saisie manuelle
- Frontend : assignation agent nom · modèle
- Tests QA : 4 profils modèles distincts (2 Claude, 2 Codex) assignés à agents
