[feature] #4116: Add test for plain == scale encoded verification for status request

[VAmuzing]

Description

While checking #4116 I found helpful to verify that scale encoded response was equal to plain with this test.
It also might come in handy when we eventually move from warp to something like axum.

Actually, why not use only SCALE in iroha_client's get_status implementation? It's win-win, isn't it?

It's unreadable if we poll it from outside, like from curl. If this feature is unused then we indeed can switch to SCALE only.

I think it is unused.
