♻️ Migrate ddns to /config/ source-of-truth architecture ♻️

Migrate ddns Docker image to the new build-time config architecture.
- rootfs/root/docker/setup/03-files.sh: rewrite to canonical form with /tmp/bin, /tmp/var, /tmp/etc, /tmp/usr handlers
- rootfs/usr/local/etc/docker/functions/entrypoint.sh: update to latest template
- rootfs/usr/local/etc/docker/init.d/*.sh: fix $(basename) UUOC; move inline comments above code lines
- rootfs/tmp/etc/: add named, dhcp, nginx, tor, named.conf, radvd.conf configs deployed to /etc/ at build time
- rootfs/tmp/usr/: add htdocs and named data files deployed to /usr/local/share/ at build time
- rootfs/usr/local/share/template-files/: delete; config now deployed via /tmp/etc/ and /tmp/usr/ at build time
