docs(wiki): extract audit log + coi audit into dedicated Audit-Log page Security-Monitoring was the largest page (~500 lines). Move the on-disk audit log format, field reference, and the full 'coi audit' command docs into a new Audit-Log page (Security-Monitoring now links to it with a short stub). Retarget inbound links (Session-Logs, Migration-Guide, Home, sidebar). Security-Monitoring 328 lines; all internal links verified.
