Replace the static one-host-per-app model with per-port routers: each
Traefik-managed port carries a subdomain (12-col PORT format) and gets a
DOMAINSUBNAME_TAG_<n> host, so one container can serve unlimited hosts.
tagsProcessorPortSubdomains stamps per-port hosts (subdomain @/empty = apex,
multi-level allowed); tagsProcessorPortRouterBlocks comments out
# TRAEFIK_PORT_<n>_BEGIN/END blocks for non-Traefik ports so unfilled
placeholders never ship (mirrors GLUETUN_OFF). Convert all 27 router apps
(subdomains seeded from HOST_NAME; headscale admin. prefix -> subdomain).
