Immugw audit logs

**Add audit logs**
The logging system in immugw is inadequate. I'm unable to verify if anyone attempted unauthorized access through brute-force methods or if there has been any data leakage. I would like to have the option to log the IP addresses of every user accessing the system.

Start by locating immugw's existing logging system and the request-handling entry points for users accessing the system. Clarify which access events and brute-force attempts must be recorded, how IP logging is enabled, and what evidence of completion should be verified before implementation.
