fix(replay): add BaseRequest body param to /replay/info

The translation middleware throws InvalidOperationException when an
action has no body parameters and a Unity client sends an encrypted
msgpack body. Tests pass without it because they post JSON directly
and bypass the middleware (no UnityPlayer User-Agent).

See RankBattleController.ForceFinish for the documented convention.
