fix: Enhances auth middleware and improves logging

Improves the authentication middleware by preventing redirection loops on the login page and adding more informative logging.

The auth middleware now checks if the requested path is '/login' and returns early, preventing an infinite redirection loop.

Also, the log message now includes the path from which the user is being redirected, which gives a better understanding of user flow.
