UI: expand the node name on hover and focus

[jlukenoff]

Problem

Currently the only way to see the full label of the node is to select it as the main node. Which can be especially annoying when using the new graph depth / full graph toggle config options.

Closes: n/a

Solution

This PR adds a mouse-enter and focus listener to the node and expands the node name when hovered or focused

Note: All database schema changes require discussion. Please link the issue for context.

One-line summary: Expands the node labels in the UI on hover/focus

We've redone the lineage graph, so this is no longer as relevant... Feel free to reopen something for hover states on the new graph.
