feat: 新增文件库功能，支持局域网文件浏览与媒体播放

Browse Source 
后端：
- 新增 ManagedLibraryRoot / ManagedFileRecord 数据模型及 SQLite 迁移
- 新增文件库服务、端点服务及定时扫描后台任务
- 新增 REST API: drives、directories、roots CRUD、files 分页搜索、文本预览
- 新增文件流端点支持视频/音频流式传输
- 数据库切换为 SQLite，Kestrel 绑定 0.0.0.0 支持局域网访问

前端：
- 管理端：磁盘浏览、目录选择、根目录添加/启用/删除/扫描
- 客户端：根目录选择、文件搜索/筛选/分页、音视频播放、文本预览
- 全新响应式 UI（桌面+移动端），CSS 变量设计系统
- HTTP 客户端支持 Vite 开发代理与生产同源自动切换
- 移除 HTTPS 强制重定向以提升移动端视频流兼容性
