Enhance settings management and localStorage integration

- Added functionality to load settings from localStorage in the SettingsManager, ensuring user preferences are retained across sessions.
- Updated the state management to initialize settings from localStorage, improving user experience.
- Refactored the UpdateService to streamline update notification preferences.
- Improved migration logic in storageHelpers to prevent duplicate migrations and ensure data integrity.
- Removed unnecessary console logs for cleaner output in various modules.
