feat(scheduler): provision 真实接线适配器(1/2) — orchestrate.ProvisionService over provision.Service

把 scheduler 的 stub provision 换成真实 provision.Service(#14)的适配器：
- 类型映射：orchestrate.NodeSpec → provision.NodeSpec（ProviderID string→int64、
  Role/Tier 转换、reality/name 字段）；CreateNode 返回 node.UUID 作 orchestrate ID。
- uuid↔int64：Destroy/RotateIP 用 provision.Store.GetNodeByUUID 解析。
- ListProviders：tier→pool(pro=premium/free=consumable) + region 过滤 + enabled 过滤。
- 依赖小接口(provisionSvc/provisionResolver)以便单测；映射全单测覆盖
  (spec 映射/uuid 解析/pool+region+enabled 过滤)。
- e2e(真实创建/销毁节点)待有机群 + 厂商凭证后验证。
