ui: Tab Improvements (animations/branding) (#7772)

* ui: Adds a tab selection animation to our app tabs

1. Replace all mentions of `magenta` with a themeable CSS property.
2. Add an easy way to inline style DOM nodes
3. Use CSS properties to add tab animation

* Fix up rendering test

* Avoid DOM noodling as much as possible
