Faraday middlewares are being called in reverse order.

With the current ordering, you might get a successful (200) response from Clickhouse with an expected content type (application/json), but the response body might contain an error message. This will cause ClickHouse to raise a JSON::ParserError or Oj::ParserError instead of a DbException.

We need to reverse the middleware order to check the response status first and only then attempt to parse the body.
