fix(omnl-portal): auth-source mapping for omdnl LXCs and LXC env fragments

Allow nginx auth snippets to use super-admin keys from paired d-bis.org VMIDs
(5820→5826 exchange, etc.), generate snippets for all 5820–5828 on deploy, and
add build-portal-lxc-env-fragment.sh for sync-time .env push with internal secret.
