Summary

fix #28224

  • Add optional user_id parameter to decode_jwt_token() for session validation
  • Validate JWT end_user session_id against provided user_id parameter
  • Update backend LoginStatusApi to accept and pass through user_id
  • Update frontend webAppLoginStatus() to support userId parameter
  • Pass embeddedUserId to login status checks in splash component

When user_id is provided, JWT authentication will fail if the session ID doesn't match, enabling detection of expired sessions. Therefore, we can dynamically update user_id.
