feat: enhance notification management and team messaging functionality

- Refactored notification handling to utilize NotificationManager for team events, improving consistency and reducing duplicate notifications.
- Introduced deduplication keys for notifications to prevent storage of identical messages.
- Updated notifyNewInboxMessages and notifyNewSentMessages functions to streamline message processing and enhance user experience.
- Enhanced rate limit message handling with in-memory tracking to prevent re-notification of deleted messages.
- Improved UI components with new animations and consistent styling for better user engagement.
- Added support for team-specific notifications, including new event types and improved error handling in notifications.
