Themes: readable with the newer UI in every built-in theme

Text and icons the newer UI paints on a selected, highlighted or accent fill now
fall back to the theme's selected or body ink where the preferred ink does not
read there (theme::readable, Tokens::accent_on, Tokens::on_selected), so
SolidCraft 95's navy-on-navy selections, 1-bit and CGA's same-colour pairs and
the light-accent title bar pill are readable. Themes that predate the
navigation bar take its hover, press, dim, field, panel and tooltip colours from
their own palette instead of their base's blue-greys. SolidCraft 95, Amber
Phosphor, One Dark, Solarized Light, Nord and Gruvbox Dark Soft get the few
colour tokens that read below 3:1 adjusted.

newer_ui_text_and_icons_stay_readable_in_every_built_in_theme walks every fill
and ink pair these surfaces paint and checks it in every built-in theme.
