refactor(server): split oversized backend services

重构 expense_claims 服务模块结构并优化差旅票据审核逻辑，
增强用户代理服务的票据类型识别，前端报销创建页面拆分为
附件模型和会话模型模块，重构提交编排器和草稿关联确认流
程，更新知识库索引，补充单元测试。

+# X-Financial Agent 协作规范
+
+## 语言规范
+
+- 所有分析、解释、计划、提交说明和最终回复默认使用简体中文。
+- 技术结论要直击重点，必要时给出可验证的文件、命令或测试结果。
+
+## 通用代码拆分规范
+
+无论写前端、后端还是算法代码，都必须主动避免“所有方法堆在一个类里 / 一个组件里 / 一个模块里”的写法。遇到类、组件或核心模块持续变大时，优先按职责拆分，而不是继续追加方法和状态。
+
+### 行数与复杂度目标
+
+- 单个类、核心组件、核心算法模块硬上限为 800 行。
+- 普通文件建议控制在 300-600 行。
+- 复杂业务文件可以接近 800 行，但必须有清晰职责边界。
+- 文件或类超过 800 行必须视为重构预警，不应继续直接追加功能。
+- 单个类不应长期承载几十个无关方法，更不应演化成上百个方法的万能类。
+
+### 拆分原则
+
+- 对外 API 尽量保持稳定，先把内部实现拆到小模块。
+- 按职责拆分：编排、状态管理、持久化、权限、文件存储、OCR/票据分析、规则审核、响应构建、序列化、UI 交互、算法策略、数据转换。
+- 新增能力时先判断归属模块；没有合适归属时新增小模块，不要默认塞回主类、主组件或主 Service。
+- 拆分必须小步进行，每次提取一个明确职责，并配套运行相关测试。
+
+### X-Financial 重点关注对象
+
+- `ExpenseClaimService`：优先拆分申请单、明细项、附件、票据分析、草稿、规则审核、权限、序列化。
+- `UserAgentService`：优先拆分知识库问答、报销预审 payload、Markdown 回复、差旅政策、表单槽位、票据分类、建议动作。
+- `OrchestratorService`：优先拆分 agent 路由、工具调用、报销查询、响应构建。
+- 前端大型 Vue 页面：优先拆分 composable、view model、样式分片、业务工具函数和子组件。
+- 算法/规则模块：优先拆分输入解析、规则匹配、评分策略、结果解释和异常处理。
+
+## 验证规范
+
+- 后端改动优先在 Docker 容器 `x-financial-main` 中运行验证。
+- 单元测试设置合理超时，避免长时间卡死。
+- 每次重构后至少运行对应服务的定向测试；涉及公共协议时补充端到端或接口测试。
