fix(routing): per-port subdomain falls back to app-name when unset

Browse Source 
An empty subdomain previously resolved to the domain apex, which would
collide on the root for any unconfigured Traefik port. Treat empty as the
app-name default (matching legacy behaviour); apex is reachable only via the
explicit @ / root sentinel.
