docs(plan): scrub stale pack subdomain + packwiz from live-arch docs

The pack./packwiz service was removed operationally long ago, but several
plan docs still presented pack. as a live caddy vhost / DNS subdomain and
render-pack.sh as a current tool. Remove those references from the
current-architecture docs (overview, caddy, tooling, uptime-kuma,
letsencrypt, mc-backup); leave the migration log (04-mods.md), superseded
banner (04-packwiz.md), commit history (12-build-order.md), and planned
landing rework (18) intact as deliberate history.
