dan select: course panel closer to the cabinet

- Course rows show the song title alone (no subtitle). In CJK languages the title is set
  in runs (ASCII / everything else) so kanji and kana keep their width; it needs the
  engine's OutlinedText.text and falls back to the engine's title without it.
- Exam values: in CJK languages the digits are narrowed beside full-width 以上/未満, with
  a little room between them; smaller size and a thicker edge, centred on the row's
  coin and right-aligned with the cabinet's.
- Exam labels (yellow_box/exam_*.png) are smaller and edged in dark ochre, centred in
  their pills.
- The 合格条件 tab, frame and exam boxes sit 5 px higher, the tab joining the frame.
- The back chip's label set across (non-CJK languages) takes a smaller size instead of
  being squeezed to the chip.
