White text on the awake timers in the dark theme

The last two attempts at this were invisible because they only moved the light
theme's ink. --wake-ink flips per theme and the dark value was left at #f5c451
throughout — a bright gold, on a pill tinted the same hue. Yellow on yellow was
exactly the report, and it was untouched by both changes made in answer to it.

--wake-timer-ink carries white for the two timers on the dark theme, where the
pill is a deep olive and white lands at 12.99:1. The light theme keeps the gold
ink: the same pill there is near-white cream, and white on it would be 1.05:1 —
gone. So this is one value that cannot be shared across the themes even in
principle, only chosen per theme.

Kept apart from --wake-ink so the AWAKE labels in the sleep & wake list stay
gold and go on matching the stripe beside them, which is the one place the
colour is carrying meaning rather than just filling in text.
