Pine b90539a013 feat(server): 统一登录+算力打通(port 阶段0-1)落地四层架构
- 登录:/auth/send-code·phone-login·wx-login·wx-phone(复用 RBAC 签发)
- 算力:services/compute_client(loopback :3000)+ /admin/compute/ping·provision
- /v1 relay 改走 compute-engine(前端不直连引擎)
- 模型:User 补 wx_openid/phone;仓储 async create+新方法
- 契约:api/schemas(auth/compute)Pydantic

"""算力引擎(compute-engine / new-api)客户端封装。
云超服算力统一经此服务消费引擎(loopback :3000,仅服务),前端不直连引擎:
模型中继 ``/v1/*`` + 管理 API ``/api/*``(建号 / 发 PAT / 额度 / 流水)。
- 引擎仅作模型计量与额度/令牌/流水,不承担身份(身份在 server-core)。
- 管理调用带引擎管理令牌(``COMPUTE_ADMIN_TOKEN``);用户侧余额/流水用其 PAT。
路径:引擎管理路由起点见 compute-engine ``controller/user.go``、``controller/log.go``、
``router/api-router.go`` 的 admin 段;以下默认路径按设计 §4.3 拟定,若与引擎实际
路由不符,仅需调整对应 ``_path`` 常量,不影响上层调用。
