Propagate max frame length to WebSocket session by aavoronin93 · Pull Request #36370 · spring-projects/spring-framework

This change ensures that maxFramePayloadLength from
WebsocketClientSpec is passed to ReactorNettyWebSocketSession.

Previously, the session used the default 64KB limit regardless
of client configuration, causing TooLongFrameException when
receiving larger frames from servers like Tomcat or Jetty.

Closes spring-projectsgh-36369
