fix(题目页): 例子输出长一点就在半格里横着滚，机房屏幕上一成的题看不全
机房两种屏上左栏只有 550px 左右，「例子 N | 输入 | 输出」每格只放得下二十来个字符， 而例子输出最长那行的 p90 有 28 个字符宽（中文按两个算），62 道题超过 32。 按这道题最长那行用实际字体量宽度：半格放得下照旧摆表；放不下就整道题的例子改成 上下排，输入、输出各占满宽；整宽也放不下的二十来道才横着滚，滚动条改成 6px 细条。 拖动分栏时实时重算。不自动折行：折出来的行学生分不清是不是真换了行。 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
