Add authentication event logging for login endpoint to enable security auditing and monitoring.

[zeropath-ai-dev]

Summary

• The Vulnerability Description:
  The login() endpoint did not record successful or failed authentication attempts, resulting in no audit trail for detecting suspicious activity or supporting forensic analysis.

• This Fix:
  We now log both failed and successful login attempts, including the username and source IP address, ensuring events are traceable and available for security monitoring.

• The Cause of the Issue:
  The application handled authentication but omitted logging, leaving a gap in visibility over access attempts and no ability to audit or investigate incidents.

• The Patch Implementation:
  The patch adds two logging statements: one for failed logins (using logging.warning) and one for successful logins (using logging.info), each recording the username and the originating IP address.
