[DubeyYash01]

Description:
This enhancement implements a session timeout feature to improve the security of user accounts in the application. After a predefined period of inactivity, users will be automatically logged out, preventing unauthorized access to their accounts if they leave the application unattended. Additionally, a warning notification will be provided to users shortly before the session expires, allowing them to save their work or extend their session if needed. This feature is crucial for safeguarding sensitive alumni data and ensuring that user sessions are managed effectively, enhancing the overall security posture of the application.
