What does this MR do and why?

The active session page is important for users to see the active sessions, manage and revoke them.

As part of the step-up authentication for admin mode, it is important to identify the session that currently have the step-up authentication enabled.

This change ensures that users can easily identify which sessions have step-up authentication enabled, providing better transparency and security management.
