fix(ui): make select trigger horizontal padding symmetric

The select trigger used pl-3 pr-2 (12 px left, 8 px right), parking the
chevron visibly closer to the right edge than the value text sits from
the left. Use px-3 so both gutters are 12 px; the gap-2 between value and
chevron and the chevron's shrink-0 keep it from crowding or clipping.
