feature: more granular styling for Flow Status by Job Id component

[vzhemchuzhnikov]

Currently there are only 2 parts that are available for styling in Flow State component: header and container.
However, container consists of much more sub-components, and it would be great to be able to style them separately.
My use case as an example: I want to only display the flow itself as it progresses, and nothing else (bound by red rectangle in the pic below). I could do that by setting display: none to every other sub-component, but currently there is no way to do that.
