MajorLinux 9e96ebb110 wiki: add wp-fail2ban logpath on Debian/Ubuntu (auth.log not syslog)
Documents the gotcha discovered during the 2026-04-30 DCAProd XML-RPC
outage triage: wp-fail2ban plugin emits via PHP syslog(LOG_AUTH) which
lands in /var/log/auth.log on Debian/Ubuntu, not /var/log/syslog.
wordpress-{hard,soft,extra} jails configured with logpath=/var/log/syslog
(common in tutorials and ansible roles) silently catch zero events.

Article includes diagnostic steps, the fix, fail2ban-regex verification,
distro cheat sheet (Debian/Ubuntu vs RHEL/Fedora vs systemd-journal-only),
and a note on why wordpress-login is unaffected.
