fix(gateway): block node role when device identity is missing

CHANGELOG.md

@@ -125,6 +125,7 @@ Docs: https://docs.openclaw.ai
 - Gateway/Security: remove shared-IP fallback for canvas endpoints and require token or session capability for canvas access. Thanks @thewilloftheshadow.
 - Gateway/Security: require secure context and paired-device checks for Control UI auth even when `gateway.controlUi.allowInsecureAuth` is set, and align audit messaging with the hardened behavior. (#20684) Thanks @coygeek and @Vasco0x4 for reporting.
 - Gateway/Security: scope tokenless Tailscale forwarded-header auth to Control UI websocket auth only, so HTTP gateway routes still require token/password even on trusted hosts. Thanks @zpbrent for reporting.
+- Gateway/Security: require device identity for `role: node` websocket connections even when shared-token auth succeeds, preventing unpaired device-less clients from invoking `node.event`. Thanks @tdjackey for reporting.
 - Docker/Security: run E2E and install-sh test images as non-root by adding appuser directives. Thanks @thewilloftheshadow.
 - Skills/Security: sanitize skill env overrides to block unsafe runtime injection variables and only allow sensitive keys when declared in skill metadata, with warnings for suspicious values. Thanks @thewilloftheshadow.
 - Security/Commands: block prototype-key injection in runtime `/debug` overrides and require own-property checks for gated command flags (`bash`, `config`, `debug`) so inherited prototype values cannot enable privileged commands. Thanks @tdjackey for reporting.
