refactor(travel): split reimbursement create workflow

完整修改内容：

- 拆分 TravelReimbursementCreateView：提取审核面板纯模型、消息操作、建议动作处理、生命周期 watcher/UI 映射、小财管家运行时、续办流程和运行时文本模型，减少主组件继续堆叠业务分支。
- 调整申请预览链路：新增本地申请意图 gate，完善复杂差旅申请的大模型复核判断、交通方式缺失/候选识别、规则中心交通费用预估合并和申请冲突处理。
- 优化小财管家流程：抽出 steward typewriter 分段策略，避免 Markdown 表格逐字闪烁；补齐跨助手 carry、字段补齐续办、文本确认提交和行程规划推荐动作。
- 调整消息与样式：移除申请预览日期 chip 样式，收敛申请卡片/报销草稿消息的展示与复制、朗读、反馈入口逻辑。
- 更新测试：将源码锚点迁移到新模块，覆盖申请预览、提交确认、小财管家续办、引导流和审核抽屉相关断言。

验证：

- node --check web/src/views/scripts/TravelReimbursementCreateView.js 及新增拆分模块
- npm --prefix web run build
- node --test web/tests/expense-application-fast-preview.test.mjs web/tests/expense-application-submit-rich-confirm.test.mjs web/tests/travel-reimbursement-guided-flow.test.mjs

说明：

- 后端/规则/容器配置/Audit 页面等工作区已有改动未纳入本提交。
- 容器内后端定向 pytest 曾运行 timeout 180s /tmp/x-financial-server-venv/bin/pytest -q <相关后端测试>，180 秒超时且超时前已有失败标记，未作为通过项记录。
- TravelReimbursementCreateView 当前仍超过 800 行，后续仍需继续拆分；本提交先把新增职责模块控制在 800 行内，阻止主类/主模块继续膨胀。
