The arrow and add icons of the dashboard libraries and templates
section use the DS icons and get their color from the color property.
The collapse button says whether the section is expanded, and the left
scroll button, which had no name, is now named "Previous".
The scroll buttons stay raw: they are round 36px buttons with no DS
equivalent. The template cards are anchors without href; they go to the
anchors backlog. A new fixture lists eight builtin templates, and a
visual test covers the cards, a card hover, the scroll buttons and the
collapsed title. No visual change.
