feat(oauth): 完善账号异常识别并在调度/展示层拦截失效 OAuth 密钥

- 新增 aether-admin provider status 模块，统一解析账号状态（禁用/工作区停用等）
- 调度器 runtime 增加 oauth_invalid 判定，跳过刷新失败或已撤销的 OAuth 密钥（REQUEST_FAILED 保留可选）
- gateway state 在 local oauth 刷新返回 4xx 时持久化失败原因并同步状态快照
- admin pool 列表/详情回填 account 状态与 scheduling 阻塞原因（account_blocked）
- 共享 catalog 的 status_snapshot payload 附加 account 字段
