feat(kit): render the chips with UiChip and UiButton

UiChip is a non-interactive label chip and renders the voice
card's chips. The pressable chips and pills are pressed toggles, so the
rail card chips, map source chips and city and place pills render through
UiButton with pressedClass, keeping their classes, attributes and the
classes other code adds. The pills now report aria-pressed.
