Direct IP retrieval method has been updated to improve accuracy in the admin system log.
This change involves modifying the IP address retrieval logic from considering the
`HTTP_X_FORWARDED_FOR` header to directly using the `ip()` method, potentially enhancing
the security and reliability of IP logging.
After the admin session expires, the system now correctly redirects to the specified admin login URL, addressing the issue where the redirect would
sometimes point to an incorrect path.
