fix(lnd-ui): manifest declared bridge 18083:80 like the spec did

Second copy of the wiring fixed in aaa89789. apps/lnd-ui/manifest.yml still
declared network_policy: bridge with a 18083 -> 80 port mapping, while
docker/lnd-ui/nginx.conf listens on 18083 directly — it has to, so it can
proxy the backend on 127.0.0.1:5678 same-origin; the cross-origin fallback
is what broke this app on http-only nodes.

Publishing a host port to a container port where nothing listens is exactly
the failure reproduced on archi-dev-box when recreating from the matching
container-specs.sh entry: :18083 refusing connections, HTTP 000. Fixing
only the spec would have left the manifest as a live footgun for any code
path that provisions this app from its manifest instead.

Now host networking with an empty ports list, matching both what actually
runs and apps/bitcoin-ui/manifest.yml, which had it right all along.
