Add audit_service.log_event() calls to track key user activities:
- auth_login: successful and failed login attempts with IP/user agent
- auth_logout: single session and all sessions logout
- task_delete: task deletion with user context
- file_upload: file upload with filename, size, and type
- admin_cleanup: manual cleanup trigger with statistics
Each event captures client IP (from X-Forwarded-For/X-Real-IP headers),
user agent, and relevant metadata for compliance and debugging.
