Closes #345

Summary

This PR fixes the authentication redirect behavior when a user's session expires.

Previously, the global Axios response interceptor redirected users to the landing page (/) after receiving a 401 Unauthorized response. This required users to manually navigate back to the login page to authenticate again.

This change updates the redirect target to /login while preserving the existing token cleanup logic. No other authentication or logout behavior has been modified.
