resolves (FR-1296)

Improve vfolder notification and error handling

This PR adds support for virtual folder notifications in the UI, allowing users to see detailed information about folder operations and errors.

Key changes:

BAIVirtualFolderNodeNotification provides a common interface for notifications targeting vfolders. Currently, actions for the vfolder explorer are not included; only the message, description, progress, and extraDescription features are provided.

• Created a new BAIVirtualFolderNodeNotificationItem component to display folder-specific notifications
• Added a reusable BAINotificationBackgroundItem component to show progress indicators
• Enhanced error handling in folder operations to provide more context
• Added support for showing mounted sessions when a folder cannot be deleted
• Improved the notification system to handle both string and React node content in extraDescription

Checklist:

• Documentation
• Minium required manager version
• Specific setting for review (eg., KB link, endpoint or how to setup)
• Minimum requirements to check during review
• Test case(s) to demonstrate the difference of before/after
