Immutable audit_log table in the scanner DB records every significant
admin action (profile save/delete, token create/revoke, PIN changes,
source add/update/delete, scheduler job changes, scan start/stop, SMTP
save, dispositions, item delete/redact). GET /api/audit_log exposes
entries newest-first. New Audit Log tab in the Settings modal renders
the table on demand. Settings modal widened 540→640 px and tab labels
set to white-space:nowrap so the six-tab row fits on one line.
