refactor(前端): 拆掉 camelCase→snake_case 转换层，契约成为唯一真相

utils/legacy.ts 是迁移期的临时层：新后端一律 camelCase，而组件读的还是
旧 Django 的 snake_case，于是在 api 层做一次递归键名重写。它自己的注释就
写了「迁移完成后这一层应当整体拆掉」。现在拆了。

代价不只是那 96 处包装：每个响应都要递归遍历整个对象重写一遍键名，而且
utils/types.ts 和 packages/contract 是两份真相 —— 手抄的那份还抄歪了好几处。

做法是按域推进，每域都用 vue-tsc 相对基线做差，确认零新增错误后再往下走。
前端的类型现在一律以契约为准，只在必要处窄化（比如 languages/template 的键
窄化成 LANGUAGE），删掉的重复定义包括 WebsiteConfig、LoginSummary、
AchievementSummary、ProblemSet、Contest、User、Profile、AdminTag、
StuckProblem 等等，其中 ClassComparison 有两个组件各手抄了一份。

## 顺带修掉的真 bug

- 管理端公告列表的「可见」开关每次都 400：列表响应被契约 omit 掉了 content，
  而更新接口要求 content 必填，toggleVisible 把列表行原样回传。而且是乐观
  翻转、不 await 不 catch，管理员看到开关动了、实际没存也没有提示。
  改成先 GET 整条再 PUT，加失败提示。

- 删有提交的题时只显示笼统的「删除失败」：前端还在 match 旧 Django 的英文
  文案，而后端返回的是 problem-has-submissions + 中文。连同另外 8 处同类
  匹配一起改成判错误码 —— 文案是后端随时能改的，match 文案改一个字就静默失效。

- SubmissionStatus.time_limit_exceeded 写成 `1 | 2`，TS 按位或算成 3，和
  memory_limit_exceeded 撞了同一个值。后端 judge/status.ts 里这是分开的
  两个码，按后端拆成 cpu_/real_ 两项。当前没有代码读这两个成员，但
  CLAUDE.md 明确要求判题状态码三处同步。

- 流程图历史翻到没有提交的那一页会直接抛：契约里 submission 是 nullable，
  被 any 掩盖成看起来非空。补了 null 分支。

## 契约里被逼出来的三处不诚实

- grade 写成 z.string()，但 averageGrade() 在没有可用数据时返回空串，
  前端三张图表拿它查 Record<Grade,...> 会查出 undefined。按实际收紧成
  z.enum([...,""])，四个查表点都补了「无评级」分支。

- difficulty 写成 z.string()。核对过生产库 dump：956 道题只有
  Low/Mid/High 三个值（761/149/46）。收紧成枚举。

- topReaction 写成 z.string()，既对不上前端渲染的 {type,count}，也对不上
  旧后端 get_top_reactions 下发的形状。改成正确形状并注明当前恒传 null。

## 明确保留 snake_case 的 54 处

判题沙箱原始输出（cpu_time/exit_code/output_md5/compile_output）、
statistic_info 内容（err_info/time_cost/ast_results）、submission_info
JSONB（is_ac/ac_time/error_number，回滚时旧后端还要读）、SQL 判题引擎的
total_rows/order_sensitive/changed_tables、WebSocket 的 submission_id、
以及数据库选项键 enable_maxkb。每一处都在类型定义旁写了为什么不能改。

language 没有跟着收紧契约 —— 它是配置项、随时可能加语言，收紧会让新语言
在后端 parse 时直接抛。改在 api 边界一处窄化。

## 另外

- utils/http.ts 整个模块已是死代码（四处引用全是 import type），删除。
- profile 的 blog/github/school/major/language 五个字段全链路空转，没有
  任何组件读，从契约到类型一并摘除（数据库列不动）。
- admin/account.ts 往 user_profile 塞的 totalScore 是 OI 模式遗留，表里
  没这一列。Drizzle 按表定义拼列名会把它静默丢弃，所以没出过错，是死代码。

验证：vue-tsc 143 → 54 条且无新增，apps/api tsc、check:routes、web build
全通过；各域响应形状逐条打接口核对过。
