Fix Bug #477: 住院医生工作站-住院检查申请详情弹窗中"发往科室"字段显示为短横线（-），未正常获取数据

根因分析：
1. 前端组件使用了错误的API获取科室列表：表单使用getDepartmentList(/app-common/department-list)
   保存的targetDepartment ID，但详情弹窗使用getOrgList(/base-data-manage/organization/organization)
   查询，两个接口返回的数据结构和ID不同，导致recursionFun无法匹配到科室名称
2. recursionFun中obj.children可能为null/undefined，直接遍历会抛TypeError
3. getLocationInfo是异步调用，handleViewDetail可能在科室数据加载完成前被调用

修复：
- 统一使用getDepartmentList(@/api/public.js)获取科室数据，与表单组件保持一致
- recursionFun增加children空值保护
- handleViewDetail改为async，打开详情前确保科室数据已加载
