fix: Memory Echo sans vol de scroll, badge IA sidebar, wizard langue

- Ne plus auto-scroller vers Memory Echo : pastille bas de page + reset scroll au titre
- Badges notes/carnets générés par l’IA dans la sidebar
- Wizard : langue du contenu = langue de la requête ; refresh carnet après création
- Voix : erreurs not-allowed/no-speech moins bruyantes
