Custom websocket port (#16658)

* feat: let custom client settings set websocket-port

A domain endpoint becomes ws(s)://<domain>/ws/id with no port, so a
WebSocket reverse proxy that cannot listen on 443 (or 80) is
unreachable. hbb_common adds websocket-port for that; list it in
KEYS_SETTINGS so default-settings and override-settings carry it.

The hbb_common bump also brings in 20d5019 (quiets smithay client
toolkit logs, rustdesk/hbb_common#620).
