Fix audit log surviving killswitch activation

Browse Source 
The audit.jsonl file (containing usernames, actions, timestamps) was
not included in the PurgeScope.ALL destruction steps. An adversary
with filesystem access after a failed or partial purge could recover
operational evidence. Added destroy_audit_log step after temp files,
before config deletion.
