Explorer: increase full hash/ids visibility

[telestrial]

Mentioned in #965 and by other Foundation team members.

Right now, we abbreviate long hashes/ids down to ~8 characters. This really cleans up the visual look of our pages. More information, by default, is not always visually appealing and it can have the function of overwhelming a user. It also isn't great for responsive design. However, we should think about ways to surface the full value for users who desire it, where it makes sense.

This probably revolves around changes to the ValueCopyable component, where we have an arrow leading to a dropdown that allows for copy and paste, navigation, etc. Maybe we add a "view full hash" button that popups the full hash and dims the background. We might also benefit from a tooltip here. There may be other solutions to look around for.
