feat(server): 新增附件关联/关联报销草稿后台任务与申请位置语义

- attachment_association_jobs：从票据夹批量关联附件到报销单，识别城市/日期并创建明细项，内存态 job 跟踪
- linked_reimbursement_draft_jobs：基于申请单异步生成关联报销草稿，调用 Orchestrator 编排，区分 succeeded/failed 终态
- application_location_semantics：抽取差旅出发/到达城市、判断具体地址/业务动作等位置语义，供申请单校验复用
- router 注册两个 job 端点，新增对应 job/语义单元测试
