fix(poll): render vote buttons with folds tokens (N4)

Poll answer buttons referenced undefined CSS vars (--accent-cyan,
--accent-cyan-dim, --accent-cyan-border, --border-color) plus hardcoded
rgba()/#fff and raw rem font sizes, so they rendered unstyled on every
non-TDS theme (invisible borders, no selected/progress state).

Replace all colors with always-defined folds tokens (Primary.* for the
selected/indicator state, SurfaceVariant.* for the resting surface +
progress fill), size/spacing/radii with config.* tokens, and the
checkbox/radio glyphs + percentage/label text with folds <Text>. The
progress-bar-behind-text affordance is preserved (folds Button has no
equivalent), now theme-reactive. Merged the duplicate checkbox/radio
indicator spans into one.
