feat: 节点/服务器批量编辑 Sheet、Server 表单协议合并修复、设备类型解析

- 新增 NodeBatchSheet 与 ServerBatchSheet，支持批量选中后一键编辑公共字段
- Server 表单：引入 mergeProtocol / buildSanitizedProtocols，过滤空字符串避免 Zod 枚举校验失败；renderGroupCard 改为具名导出供批量 Sheet 复用；优化嵌套错误提示递归取第一条
- 新增 parseDeviceType 工具函数，从 User-Agent 解析设备平台（iPhone/Android/Mac 等）
- 用户列表：登录标识旁展示设备平台 Badge
- 注册安全设置表单：引入 Textarea 组件并完善字段布局
- 类型定义补充及 i18n 本地化更新
