fix(k3s): 持久化香港控制面磁盘调度缓解

Browse Source 
原因：香港虚拟磁盘在低吞吐下仍出现高同步写延迟，触发 etcd slow apply、Handler timeout 和 PostgreSQL API Server 连通性异常。\n\n影响：新增仅针对香港根块设备的 mq-deadline 配置脚本，应用时不重启 K3s，并提供显式 rollback 恢复 none；运行手册明确该项仅为缓解，不能替代高性能云盘。\n\n验证：新香港节点同步写探针从 13.28ms 降至 6.25ms；bash -n、ShellCheck、manual-release-test.sh 通过。
