fix: persister l'état du Pomodoro Timer avec localStorage

- Sauvegarder l'état du timer (mode, temps restant, état running, sessions) dans localStorage
- Restaurer l'état au montage du composant
- Le timer ne se réinitialise plus quand le modal se ferme et se rouvre
- Simplifier le PomodoroModal pour utiliser children directement
