feat(web): 报销单新增关联申请单门控与草稿检测流程

- 新增 travelReimbursementAssociationGateModel，查询可关联申请单/草稿报销单并生成跳过/选择/单独新建动作，区分差旅费与业务招待费类型
- travelReimbursementApplicationLinkModel 补充 buildLinkedApplicationReferenceIndex/buildRequiredApplicationActions 等关联构建逻辑
- useTravelReimbursementSuggestedActions 接入 select_required_application/skip 系列动作，'我要报销'入口改为先走关联门控
- useWorkbenchAiActionRouter 新增 SKIP_REQUIRED_APPLICATION_LINK/SKIP_REIMBURSEMENT_DRAFT_CHECK 动作分发
- useWorkbenchAiExpenseFlow 暴露 startAiReimbursementAssociationGate，stewardPlanModel 待处理流程适配
- 新增 workbench-ai-action-router、workbench-ai-reimbursement-association-gate 测试并更新 guided-flow、steward-plan 测试
