feat(阶段4): 测试用例压缩包上传与下载

POST  admin/test-cases
  GET   admin/problems/:id/test-cases   （返回 zip 二进制）

落盘格式必须与判题沙箱镜像的约定一致（沙箱直接读挂进去的目录），已用真判题验证：
上传 zip → 建题 → 提交 Python 解法 → 沙箱读到用例并判出 Accepted。

安全与健壮性上比旧后端多做的几件事：

- **zip slip 从设计上进不来**：不遍历压缩包条目，只按精确文件名（`N.in`/`N.out`/`N.sql`）
  取内容，条目名一律不参与路径拼接。实测带 `../../etc/passwd` 条目的包能正常处理，
  且只取到 1.in/1.out。
- 单文件 32MB、解压后总量 128MB、测试点数 500 的上限，防 zip bomb 与写满磁盘 ——
  旧后端一概没有，机房那台机器盘写满之后判题也会一起挂。
- 坏 zip 返回 400 而不是 500。

对齐旧后端的细节：CRLF→LF 归一；`stripped_output_md5` 按 Python `bytes.rstrip()`
的口径只剥尾部 ASCII 空白后再算（实测与 hashlib.md5 结果一致）；编号从 1 起连续、
遇缺口即停；SQL 包至少 2 个测试点（题目页会展示测试点 1 的期望结果，只有一个时
学生可以对照着硬编码 AC）；目录 0710、文件 0640。

## 顺带修掉一个只在判题时才暴露的路径 bug

config 里的相对路径（data/test_case、data/avatar、data/upload）原先按进程 cwd 解析，
而起服务的方式会把 cwd 切到 apps/api/，于是测试点落在 apps/api/data/ 下 ——
但 docker/compose.dev.yml 把**仓库根**的 data/test_case 挂进判题沙箱。两边不是同一个
目录，新传的测试点判题时会「找不到测试数据」，且只在真正判题时才暴露。
改成一律按仓库根解析，实测沙箱能看到新传的目录。
