feat(k8s): M14 Namespace 管理看板（资源配额 + 命名空间 CRUD）

- 后端: ListNamespacesDetailed/CreateNamespace/DeleteNamespace/ListResourceQuotas/ListLimitRanges
- 后端: GetNamespacesDetail handler (6 API calls aggregate, not N×3)
- 后端: CreateNamespaceHandler + DeleteNamespaceHandler (system NS protection)
- 前端: NamespaceManagementPage.tsx (~280行) — 表格+概览卡片+创建/删除弹框
- 路由: GET/POST/DELETE /:clusterCode/namespaces + GET /namespace/:ns/detail
- 验证: 9/9 通过 (urllib), TS 零错误, Vite 构建成功
