Real root cause turned out to differ from the original TODO: there was
no broken global CustomLog, mod_vhost_combined was already logging
every vhost without its own CustomLog into other_vhosts_access.log.
Added a dedicated CustomLog per real site anyway for easier incident
review, verified live with curl against all 7 domains after reload.

README's public-access table and "previously resolved" summary now
reflect the dyndns injection fix and the TSIG-permission regression it
uncovered. Adds two open TODO items found during that audit: the dyndns
app's lack of real per-user auth binding, and the fact that access
logging for every real vhost on this host is currently a no-op.
A stray /var/www/html/.htaccess (dated 2025-02-18, predating everything
else in TODO.md) was silently requiring HTTP Basic Auth for jayfield.org
and www.jayfield.org's shared DocumentRoot, 401ing every real visitor to
the intentionally-public static site. Removed (backed up, not deleted).
Also adds a README table auditing which public hostnames do/don't
require credentials, prompted by checking this.
Moved Portainer's HTTPS UI behind an Apache reverse proxy on its own
subdomain (portainer.jayfield.org) instead of publishing it directly on
:9443 with a self-signed cert, which HSTS's includeSubDomains policy made
unreachable in Firefox with no click-through exception. Same pattern as
the existing web.jayfield.org/cloud.jayfield.org proxied subdomains: DNS
A record, Apache vhost proxying to 127.0.0.1:9443 over HTTPS, real
Let's Encrypt cert via certbot, standard HSTS header. Portainer container
recreated to bind 9443 to loopback only; verified end-to-end (cert chain,
HSTS header, redirect, and that :9443 is no longer reachable externally).
Firefox refuses https://alpha.jayfield.org:9443 with
MOZILLA_PKIX_ERROR_SELF_SIGNED_CERT and no click-through: the
includeSubDomains HSTS policy on the real alpha.jayfield.org vhost pins
the hostname to trusted-cert-only HTTPS on every port, but Portainer
still serves its stock self-signed cert directly on 9443. Records the
root cause and the planned reverse-proxy fix; no server changes made yet.
Records the host's service inventory, setup runbook, mail account list,
sync plan, package diff vs. clean install, and hardening TODOs, including
today's SSH hardening (key-only, no root login) and the fail2ban sshd
findtime fix for a low-and-slow brute-force evasion pattern.
