feat(tools): 添加 Ulthon Admin 前端静态构建工具

- 新增 `tools:ua:build` 命令，用于合并前端模块文件
- 添加构建配置文件 `ua.build.json` 定义源文件和输出
- 引入基础服务类 `ToolsUaServiceBase` 处理路径和配置读取
- 创建命令基类 `ToolsUaBuildBase` 实现文件合并逻辑
- 注册新命令到 UlthonAdminService 服务容器
- 提供完整的模块化前端代码结构（core、common、table、listen、api、utils）
- 添加详细的使用说明文档 README.md
- 包含示例 Scheme 文件展示功能
