修复权限管理页面错误

1. 修复 ApiPermissions.vue 中的数据绑定错误
   - 从 axios 响应中正确提取 .data 属性
   - 修复 loadPermissionData、loadMonitoringData、save 函数

2. 禁用 FastAPI 响应验证
   - 在 api_permissions.py 中添加 response_model=None
   - 避免 Pydantic 验证错误

3. 注册权限监控 API 路由
   - 在 router.py 中导入并注册 permission_monitoring 模块
   - 修改 permission_monitoring.py 的路由前缀
