fix(localdb): re-bind ASPNETCORE_HTTP_PORTS surface, not just ASPNETCORE_URLS

Browse Source 
The Kestrel re-bind read only urls/ASPNETCORE_URLS. The aspnet:8.0+ base images
set ASPNETCORE_HTTP_PORTS=8080 (all interfaces) as the CONTAINER default in place
of ASPNETCORE_URLS, so a driver node that never sets URLS fell straight through to
Kestrel's localhost:5000 default — silently moving its health/metrics surface to
loopback when the sync listener took over Kestrel. Now falls through URLS →
HTTP_PORTS/HTTPS_PORTS (wildcard, all-interfaces) → localhost:5000, mirroring
Kestrel's own source precedence. Found on the docker-dev live gate (central nodes
were fine — they set ASPNETCORE_URLS=9000 explicitly).
