Per demo feedback on the T-234 status-bar popover: collapse the -hc
theme rows into a single 'High contrast' toggle at the top (applies the
chosen base theme's -hc sibling live, falling back to the base when none
exists); list base themes only, sorted by display name; widen 240->280
and ellipsize rows so 'Catppuccin Mocha' no longer wraps; swap the swatch
dot for the Phosphor palette icon; lowercase the bar label to match the
all-lowercase status bar (proper case kept in the a11y label).
New pure theme_families helpers (base/sibling/resolve), unit-tested.
Modal picker_view consistency + the status-bar right-alignment remain on
T-237.
