Carry the new palette into every remaining colour

The group chat bar drew white text on the old header token, now light;
it sits on near-black instead. Status, class, routine-kind, goal and chart
colours move from greens and navies to the reference scheme: orange for
met and held, near-black for fine and neutral, deeper orange then red as
standing worsens. Home's ring and kept-day leaves and Progress's bars use
the full accent so they read on grey.
