Design tokens have fallen out of sync

[Alex Pate]

Some of the tokens seem to have fallen out of use:

Example:
Focus/active state for inputs are hard-coded rather than coming from a design token
https://github.com/kalohq/ui/blob/master/src/components/input/input.css#L37

border: 1px solid var(--grey600);

vs
https://github.com/kalohq/ui/blob/master/config/design-tokens/input.yml#L17

  INPUT_ACTIVE_BORDER:
    value: 1px solid {!BLUE500}
