feat(k8s): M11 StatefulSet/DaemonSet 详情页 — WorkloadViewPage 重写 + YAML 路由冲突修复

后端:
- routes.go: 为 statefulsets/daemonsets 注册专门 YAML 子路由（Gin radix tree 冲突）
- kubernetes.go: GetResourceYAMLNS/UpdateResourceYAMLNS 添加 URL path fallback

前端:
- WorkloadViewPage.tsx 重写: 修复 kind 提取 bug(useLocation) + 更新策略/选择器/PVC模板/InitContainers
- NamespaceResourcePage.tsx: handleDetail 添加 STS/DS 点击导航

验证: DS YAML API 200 ✅ | DS Detail 200 ✅ | Dep YAML 200 ✅ | SPA路由 200 ✅ | TS零错误 ✅
