fix: 修复 HR/企业端进不去（非 Tab 页误置于 Tabs 组内）

- 将 (enterprise) 组内 6 个非 Tab 屏企业页（enterprise-certification/audit-report/candidate-detail/hr-evaluation/job-publish/operation-rules）移回根目录 app/，与求职端 job-preference 结构对称
- 仅保留 4 个 Tab 屏（enterprise-overview/job-management/talent-recommendation/enterprise-chat）+ _layout 在组内
- 修正移回文件相对引用 ../../src → ../src
- 根因：enterprise-certification 被塞进 Tabs 组但非 Tab 屏，router.replace('/enterprise-certification') 进入后 Tab 导航器因 route 未声明而导航失败/白屏，导致『HR 进不去』；移出后成为干净栈页，身份认证→企业端链路通畅
