feat(manager): 专家审核页修改按钮跳转独立编辑页

参考 /admin/experts/new 模式:
- 新建 ry-vue3/src/views/manager/ExpertNew.vue (15 字段, 1:1 抄 admin 版, 仅 goBack 跳 /manager/experts)
- router 加 /manager/experts/new 和 /manager/experts/edit/:id 两条路由, 复用 ExpertNew 组件
- manager/Experts.vue 操作列 "修改" 按钮 → router.push('/manager/experts/edit/:id')
- 加 route watcher, 从编辑页返回时自动重载列表
- 新建专家按钮保留原 dialog (按用户当前只要求改修改按钮)
