Enhanced ERP Notification Features

@Team we've rebuilt our Notification system with significant improvements.
Clear All Option: We've introduced a "Clear All" feature, allowing users to remove all notifications with a single click, streamlining the user experience.
Individual Removal: Users now have the ability to delete notifications one by one, and added animations for each notification when cleared.
Dynamic Notification Counts: As notifications are cleared, the notification count dynamically adjusts, ensuring users always have an accurate overview of their unread notifications.
