fix(sidebar-text-highlight): Improve component to highlight text and use in navigation

[phixMe]

Problem

Old component relied on parent derived state to calculate ranges and would not be suitable for a unit test or usable outside the context of this specific place in our application.

Changes

-[x] Rewrite component to be self-contained, usable elsewhere, and retain it's
-[x] The component correctly inside the list renderer.

Does this work well for both Cloud and self-hosted?

Yes

How did you test this code?

Text now highlights and provides a cleaner and more ubiquitous interface.
