[Bug] When CU RPC call errors, different behavior is shown on the Block page and the transaction signature page.

Problem

On the block page, when CU RPC call errors out we just show an unknown indicator on the page. However, we just don't show the line item on the signature page if the CU RPC call errors out.

Solution

The behavior should be the same across the pages instead of different. Ideally we do not show the unknown as that is confusing to the visitor.

Do you have block / example page I can look at?

[waldrobi]

I actually believe we should be explicit on it Not Available or not Not Supported Slot or something. I strongly dislike when UI components just disappear

Note that the actual behaviour is that a 0 returned and not Unknown or it doesn't show. I don't think that's ideal either
