Fixes (#23130)

* respect section hiddenFields when detecting config overrides

* change audio events to audio detection to match docs

* add field messages for object and review genai

* add more config messages

* more messages

* add guard to prevent race when adding camera dynamically

* fix duplicate websocket messages from zombie connection under react strict mode

detach ws event handlers before close() in WsProvider cleanup so a CONNECTING socket's deferred onclose can't schedule a reconnect after the next mount resets the unmounted guard, which was spawning a second live ws and duplicating every message

* fix double event publishes for stationary objects with attributes
