feat(成就): 下架三个拿不到的成就、理顺稀有度和图标；接口多给本班几人有和「本班」卡片

- 0032：下架六边形战士（判题机只剩 3 种语言）、坚持三天/一周（按天算基本拿不到）；
  不撞南墙改白银、屡败屡战改黄金；百发百中换 💯、屡败屡战换 💪，不再和别的撞图标；
  代码行数只算做对的、空行不算，并按新口径重算所有人；已经拿到的一个不收回
- 奖杯收藏家只数上架的成就（判题结算、补发重算、0032 存量一起改）
- GET /achievements：每个成就带全站几人有、本班几人有；看自己时带「本班」（最近拿到、成就最多前五、自己第几）；
  隐藏成就同一串拿到一档就整串亮出来；连续几周给「现在连着几周」而不是历史最长
- 删掉只有旧成就页在用的 /achievements/summary
