Fix boundary bugs, route side effects through MoodLogger, add data listeners

- Fix ExtensionDataProvider <= boundary to < in date queries (prevented cross-day leaks)
- Replace force-unwraps with guards and add error logging in DataControllerGET and ExtensionDataProvider
- Route DayViewViewModel update/delete through MoodLogger.shared (was duplicating side effects)
- Add data listeners to InsightsViewModel and YearViewModel for cross-tab refresh
- Add HealthKitManager.deleteMood(for:) for single-date cleanup
- Add SharedModelContainer.isUsingInMemoryFallback flag with critical logging
- Add analytics events: entryDeleted, allDataCleared, duplicatesRemoved, storageFallbackActivated
