fix: 修复Agent头像显示和结果弹窗问题

主要修复:
- 恢复Agent真实头像显示（替换emoji为实际图片）
- 删除自动跳转到ResultPageV2的逻辑
- 修改ResultModal支持动态内容显示
- 根据不同订单班显示对应的方案信息

优化内容:
- 重构Agent系统，每个订单班独立管理Agent配置
- 删除不需要的ResultPageV2组件
- handleViewDetails改为在新标签页打开

影响模块:
- web_frontend/exhibition-demo/src/components/ResultModal.tsx
- web_frontend/exhibition-demo/src/pages/WorkflowPageV4.tsx
- web_frontend/exhibition-demo/src/App.tsx
- web_frontend/exhibition-demo/src/data/terminalSimulations/*.ts
