Force idle stream to 5min and hide setting (#6810)

* Hide "Allow orbit in sketch mode" setting from the app

The ability to orbit while in sketch mode is not well-tested or
well-used, so we should pull it from the app. The easiest way to do that
is leave the setting in the WASM definition, but configure the setting
to be uneditable from the interface.
