fix: unbundled ISO uses full first-boot script with all container fixes

The unbundled build was generating a 73-line inline script that only
created FileBrowser. This meant no lnd.conf, no UI sidecars, no
--add-host DNS fix for any app. Now uses the full first-boot-containers.sh
which handles both bundled (load tarballs) and unbundled (pull from
registry) modes, and includes all fixes for LND config, nginx sidecars,
and DNS resolution.
