[FEATURE] Auth logs for Flowise UI login so Fail2Ban can block UI login attempts.

[SuperPauly]

Describe the feature you'd like Logs indicating the IP of people who have attempted to login via the Flowise UI and the local system or UTC+0 Datetime stamp with each entry.

Additional context Fail2Ban needs some sort of text log file to see which IP's it should ban or not. I have had a look but I still don't see much in terms of attempted logins.

I have tried with several combinations of log level and enabling debug and I still can't seem to find any IP addresses in the Docker /root/.flowise/logs/ directory when I attempt to login with false credentials.
