feat: Wizard IA + Export PDF + fixes blocs

- Wizard IA: création de carnet complet (étudiant/prof/ingénieur)
  - 3 profils, choix niveau, nombre de notes (3-12)
  - Étapes numérotées, messages de progression, écran de succès
  - Notes riches avec callouts, toggles, équations, colonnes
  - Structured View auto-créé avec propriétés Statut/Difficulté
  - Embeddings en arrière-plan
- Export PDF: clone le DOM réel, rend KaTeX, préserve couleurs callouts
- Fix: boutons toggle/callout en hover-only
- Fix: parsing JSON robuste (backslashes LaTeX)
- Fix: flushSync warning (queueMicrotask)
- Fix: drag handle clamp viewport
- Bouton wizard dans la sidebar (✨ à côté du +)
- i18n FR/EN complet
