style: auto-format with black + isort + prettier [skip ci-format-check]

问题：ci-builder-persist 持久化 builder 的 buildkit 层缓存偶尔出现'幽灵命中'：
COPY apps/web/ ./ 步骤认为自己没变（实际文件已改），导致 vite build 不执行，
打出来的 Web 镜像前端文件是旧的。

修复原理：
把 apps/web/ 目录的 git tree hash 作为 build arg 传入 Dockerfile。
buildx 把 build arg 值作为缓存键的一部分，hash 变了 → RUN 步骤缓存失效 →
vite build 必须重新执行。依赖层（npm ci）不受影响，仍然正常缓存。

改动：
1. web.Dockerfile：新增 ARG SOURCE_HASH，在构建步骤写入 .cache_bust 文件
2. docker_build_push.sh：Web 镜像构建时计算 git tree hash 并传入
3. docker_build_only.sh：同上

验证：
- 合并后触发 push 到 develop
- 查看 Build Staging Web Image 日志，确认输出 Web cache bust: SOURCE_HASH=xxxxx
- 修改 apps/web/ 下文件再次 push，确认 SOURCE_HASH 值变化且 vite build 执行
