feat(client): 完成 P3 业务页联动闭环（D6/D8/D10/D11）

- 待办：列表/详情 + approve/reject/return/transfer（D6） - 报销：列表/详情 + create/submit/withdraw/pay（D8） - 票据：列表/上传/OCR轮询/绑定/预览（D10） - 统一：Api types + 错误映射 + react-query缓存失效（D11）

+## 6. 页面现状（P3）
+- 待我处理：列表 + 详情 + `approve/reject/return/transfer` 动作。
+- 我的报销：分页列表 + 详情 + `submit/withdraw/pay` 联调入口。
+- 票据中心：分页列表 + 上传 + OCR 轮询 + 绑定 + 签名预览。
+- 审计工作台：分页筛选已落地。
+
+## 7. 状态管理与错误语义
+- 引入 `@tanstack/react-query` 统一查询缓存与失效策略。
+- 错误文案统一映射在 `client/src/api/errorMessages.ts`。
+- API 层保留后端错误码原文，前端仅做可读化。

 ## 6. 风格资源复用策略（锁定）

 - 采用“复制到 client + 单向同步”，不做跨仓软链与自动联动。
 - 如需同步风格，请记录来源 commit 并通过评审。
