refactor(api): 渠道与存储管理端点通用化，端点层零目标特色

- schemas 新增公共 ManageRequest(target+action+params) 与 StorageAction 词汇表
- endpoint 层收敛为 POST /notification/manage、/storage/manage 两个通用接口，
  不再定义任何渠道/存储特定的名称、参数与响应字段，前端上送参数原样透传
- chain 层 manage_channel/manage_storage 接受字符串标识纯透明转发，
  StorageChain 移除全部特色管理方法
- FileManagerModule 新增 storage_manage 统一入口，模块返回归一化为
  {success, message, data}；wechatclawbot channel_manage 同步归一化，
  路由标识兼容枚举名/值/对象
- dashboard 与 agentopsassistant 的用量查询改走 manage_storage(usage)
- 新增 10 项存储契约守护测试，通知侧补充 3 项链透传与字符串路由测试，
  API 守护测试对 ManageRequest 开放映射按设计豁免
