refactor: almost ready for v0.1.0

- 优化 `Shared` 中的 `Codec` 枚举，增加显示名称并添加 `isLossyAudio` 函数
- 简化 `Codec`、`VideoSource`、`AudioSource` 和 `CameraFacing` 枚举中的 `fromString` 方法
- 将 `fetchConnectedDeviceInfo` 改为挂起函数以支持协程
- 清理 `PreferenceMigration` 和 `ScrcpyOptions`，提高可读性
- 更新 `Settings` 类，添加 `isDefaultValue` 挂起函数
- 改进 `DeviceWidgets`，增强状态管理和 UI 响应性
