Migrate journal entries to CoreData for iCloud sync (build 33)
- Add JournalEntry CoreData entity (syncable=YES): id, monthKey, note, moodRaw, rating, completionTime, createdAt
- Rewrite MonthlyCheckInStore: CoreData as primary storage, same public API
- One-time migration from UserDefaults triggered after store loads
- MonthlyCheckInCard: @FetchRequest on JournalEntry — reactive to iCloud sync
- MonthlyCheckInView: onReceive NSManagedObjectContextObjectsDidChange to refresh @State vars on sync
- Stats cards: observe NSManagedObjectContextObjectsDidChange instead of UserDefaults
- ChartsViewModel.completedMonthKeys: remove MonthlyCheckInStore dependency (data-driven)
