refactor(契约): 判题状态码收进契约唯一一份，并收紧 18 处 as any

- 状态码常量与 judgeStatusSchema 移到 packages/contract/src/judge-status.ts，
  后端 judge/status.ts 只再导出；前端 SubmissionStatus 枚举加编译期断言对齐契约
  （实测改坏一个码会当场类型检查失败）
- 类型逃逸 22 处降到 4 处：collab/handler、pagination、configUpdate、
  ExerciseManager、ProblemSubmission、pk.vue tooltip；剩下的是词云插件无类型、
  生成的 .d.ts、skulpt 和 TextEditor
