🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

补充运行状态的 API 操作白名单。

Line 856 将 APIGetVmStartingCandidateClustersHostsMsg 传给 validateOperationByState。但 compute/src/main/java/org/zstack/compute/vm/AbstractVmInstance.java 的 VmInstanceState.Running 白名单只包含 GetVmStartingCandidateClustersHostsMsg，不包含 APIGetVmStartingCandidateClustersHostsMsg。因此，运行中的 VM 调用该 API 时会在 Line 857 到 Line 860 直接返回 SysErrors.OPERATION_ERROR，不会发送内部查询消息。这与本 PR 允许运行中 VM 查询启动候选主机的目标不一致。

请将 APIGetVmStartingCandidateClustersHostsMsg.class.getName() 加入 VmInstanceState.Running 的允许操作列表，并覆盖 Running 与 Stopped 状态测试。

建议修复

补齐 HA_PRECHECK 和 HA_START 的分配链路

两个枚举值目前仅在 HostAllocationPurpose.java 中声明。仓库中没有赋值、比较、switch 分支或测试引用。HostAllocatorSpec.getPurpose() 也没有下游读取，因此新用途不会改变候选主机过滤行为。补充消息传递、过滤器分支和测试；否则删除这两个枚举值。
