Subject: [PATCH] fix(webui): refresh stale per-port Subdomain tooltip
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The Subdomain field's help text still said it inherits CFG_HOST_NAME and that
the label-generation refactor was pending — both untrue now that per-port
subdomain routing has shipped. Reword to: empty -> app-name default, @ ->
domain apex, multi-level supported.
