fix(ci): pull API base image from Huawei SWR instead of DaoCloud

Staging publish failed resolving python:3.12-slim through m.daocloud.io; the web image already uses the reachable SWR docker.io/library path.

+## BUG-333 | staging 发布 API 镜像时 DaoCloud TLS 握手超时
+
+- 状态：resolved
+- 首次发现：2026-08-20
+- 最近更新：2026-08-20
+- 影响面：Gitea `backend-quality-gate` 的 `publish` job、`deploy/railway-api.Dockerfile`、`xiaoxin` runner 拉官方基础镜像
+- 用户现象：`validate` 通过后 `Build and publish exact-SHA ACR images` 在 API Dockerfile 第一行失败：`Head "https://m.daocloud.io/v2/docker.io/library/python/manifests/3.12-slim"` TLS handshake timeout。
+- 触发条件：向 `staging` 推送后 publish 构建 `deploy/railway-api.Dockerfile`。
+- 根因：API 基础镜像仍走 DaoCloud 代理。同一 runner 已验证可达华为 SWR / ECR / ACR；Web 镜像早已改用 `swr.cn-north-4.myhuaweicloud.com/ddn-k8s/docker.io/library/node:22-alpine`，API 未跟上。
+- 修复：API `FROM` 改为与 Web 相同的华为 SWR `docker.io/library` 路径，指向 `python:3.12-slim`。不改运行时端口、pip/apt 镜像或 ACR 目标仓库。
+- 验证：`tests/test_railway_deployment.py`、`frontend/tests/staging-backend-workflows.test.ts`。远端 publish 由本提交后的 Gitea quality gate 验收。
+- 防复发：API/Web 官方基础镜像必须走华为 SWR `ddn-k8s/docker.io/library`，合同禁止 `daocloud`。不要为了重试再加一套 `for attempt in 1 2 3`，workflow 里该循环次数已被合同锁死为 5。
+- 相关记录：BUG-149、BUG-150、BUG-332
+- 复发自：无
+- 修复版本：待提交
