feat(提交结果): 没通过时显示「通过 x/y 个测试点」；编译失败不等三次就能用 AI 分析

学生拿不到 info（每个点带 output_md5，只给管理员），测试点表格从来只有管理员看得见，
学生这边只有一句「答案错误」—— 从 2/8 交到 6/8 的人，感受是连输五次。

- 提交详情新增 caseSummary，后端从 info 数出通过数下发，不放开原文。
  比赛提交、SQL 题（被杀的测试点会 break，total 偏小）、无逐点结果时为 null
- 结果面板标题缀上通过数并加进度条，提交详情页标题同步；一个都没过时不缀
- POST /ai/hint 对编译失败跳过失败次数门槛，throttleAi 照旧；前端显示条件同口径
