feat: 劳务协议编辑改独立页 + 去 el-card 圆角框

- 新增 LaborProtocolEdit.vue (独立页, 新建/编辑复用, 跟 ExpertNew.vue 风格一致)
- 加路由 /admin/labor-protocol/new 和 /admin/labor-protocol/edit/:id
- LaborProtocol.vue 删 el-dialog + 改为 router.push 跳转
- 新增 .form-card.nested { border: none; box-shadow: none; } 去 el-card 圆角框
- 新增 _self/admin_labor_protocol.md 审查报告
