Fix the lobby art not fading out (#91637)

## About The Pull Request

ports a fix from
https://github.com/Monkestation/Monkestation2.0/pull/6991

https://github.com/tgstation/tgstation/pull/76772 accidentally broke
most instances of using `/atom/movable/screen/splash`, bc now the client
needs to be third instead of second argument to `new
/atom/movable/screen/splash`... yeah.
