fix: corriger l'erreur CSP et le nettoyage HTML des notes

- Remplacer l'audio base64 par Web Audio API dans PomodoroTimer pour éviter les erreurs CSP
- Ajouter une fonction cleanHtmlContent pour correctement décoder les entités HTML
- Corriger l'affichage des notes pour supprimer les caractères parasites (&nb-, etc.)
