feat(deploy): 切换宁波单节点生产拓扑

移除已停用的香港 API、Web、Worker 和边缘 Service 渲染结果，将 Worker 与容量控制器固定到宁波单实例，并在发布成功后清理旧香港资源。\n\n容量控制器忽略最大副本为零的站点，集群环境允许不再声明香港主机；单节点 production acceptance 不再依赖香港 Service、Deployment 或 SSH 回退。\n\n验证：Go 全量测试与 go vet；迁移安全检查；Kustomize 单节点渲染；ShellCheck；cluster release、production acceptance 和 manual release 测试。
