Reduce prop drilling in Offcanvas Inspector back button

[getdave]

Let's explore reducing the prop drilling here by retrieving values directly from the stores instead.

    It may simplify things if this component just received a "clientId" and handles everything using useSelect/useDispatch internally. There doesn't seem to be a valid reason for all the prop passing down (unless I'm missing something). For the record, I know this is not entirely introduced in this PR :)
