fix(ui): prevent title cards from flickering when quickly hovering across them (#3349)

* fix(ui): remove opacity classes from transition enter and leave props

The flickering was caused by the opacity classes in the `leave` prop to take effect as the
transition ends; when the `leaveTo` prop classes are no longer applied, but the `leave` prop classes
are still applied.

* fix(ui): resolve transition issues for all components

1. Remove opacity classes from `enter` and `leave` props
2. Fix some class name typos
3. Remove transform classes since those are automatically applied as from TailwindCSS v3.0
4. Narrow down `transition` classes to only the properties being transitioned in Transition components
