Resolves #10 Todos: Vollständige Implementierung

- Todo-Modell (V8-Migration): dueDate, reminderDate, isCompleted, completedAt
- AddTodoView + EditTodoView: Fälligkeit, Erinnerungspush, intelligenter Reminder-Default
- TodayView: Fällige Todos-Sektion mit Fade-out (5 s) nach Abhaken
- PersonDetailView: Todo-Sektion, tap-to-edit, Glockensymbol, Fade-out
- Momente: tap-to-edit, Favoritenstern inline, Löschen-Button in EditMomentView
- DeletableMomentRow entfernt (Swipe durch direkte Interaktion ersetzt)
- Geburtstage-Sektion zwischen Unternehmungen und Todos in TodayView
- Lokalisierung (de/en) und Tests aktualisiert
