feat: Flutter 客户端 App + Web UI APK 下载入口
- 新增 Flutter 跨平台客户端项目 (clients/flutter/)
- 29 个 Dart 文件: 服务层/状态管理/5个页面/BLE配网
- BLE 蓝牙配网: 扫描设备、写入WiFi凭据、配网状态监听
- HTTP API 客户端: 覆盖全部端点 (播放/场景/WiFi/视频/配置/文件/插件)
- WebSocket 实时通信: 事件流 + 自动重连
- 暗色主题 Material 3 UI, 中文界面
- Android 配置: minSdkVersion 21, BLE/网络权限
- PRD 产品需求文档 + 开发任务看板
- Web UI 添加 APK 下载入口 (routes.rs)
- 下载弹窗 + 二维码 + /download/{filename} 静态文件路由
- BLE 插件增加自动重连循环 (ble/mod.rs)
- BLE 默认设备名修正为 'Showen' (config.rs)
