feat: 打通录音核心链路，连接前后端命令

- 重构 capture.rs：添加 start_recording/stop_recording 支持真正的开始/停止控制
- 更新 AppState：引入 RecordingHandle 字段管理录音状态
- 重构 commands.rs：start_recording 立即返回，stop_recording 停止并保存文件
- 新增 recognize_file/recognize_last_recording 命令
- 前端 RecordPage：调用真实后端命令，监听 recording-stopped 事件自动识别
- 前端 FileConvertPage：连接 recognize_file 命令，支持导出识别结果
- 前端 SettingsPage：通过 save_config 持久化配置，支持配置加载
