fix(ci): 修复build-staging在PR模式下被跳过的问题

问题1 - cancel-in-progress踩踏：
- 将构建类job拆分到独立的 .gitea/workflows/ci-build.yml
- 新workflow cancel-in-progress: false，构建启动后不被新commit顶掉
- 原ci-cd.yml保留4个门禁job（validate/unit/integration/frontend-lint）
- 门禁workflow保持cancel-in-progress: true，快速响应新commit

问题2 - buildx name冲突：
- 所有 docker buildx create/use/rm 的 ci-builder 改为动态名
- 动态命名：ci-builder-${{ github.run_id }}-${{ github.job }}
- 每个job每个run独立builder实例，多runner同机构建不冲突

变更统计：
- ci-cd.yml：910行 → 406行（仅门禁）
- ci-build.yml：新增535行（构建+部署+E2E）
- buildx实例：10处引用全部动态化
