feat(chart): add webapp.service.extraPorts to expose extra ports on the webapp Service

Adds an `extraPorts` hook to the webapp Service template so additional
in-cluster ports can be merged onto the existing `<release>-webapp` Service
via values, without a separate Service or TLS. Primary use: exposing the
embedded s2-lite :8080 port for realtime streams in TLS-off environments
(e.g. GameWarden) where the umbrella's tls-gated webapp-internal Service
doesn't render. Default is an empty list, so existing renders are unchanged.
