添加端口配置和图标支持

在 `LocalDrop.csproj` 中添加了 `LocalDrop.ico` 的嵌入资源支持，并设置了 `CopyToOutputDirectory` 属性。
在 `LocalDrop.json` 中新增 `port` 键，值为 `27431`。
在 `MainWindow.xaml.cs` 中添加了获取当前目录和文件路径的方法，并设置窗口图标。
在 `NavItemReceiver.xaml.cs` 和 `NavItemSend.xaml.cs` 中使用从 JSON 配置读取的端口值替代硬编码的端口号。
在 `NavItemSetting.xaml` 中添加了用于输入和保存端口号的 UI 组件，并在 `NavItemSetting.xaml.cs` 中实现了相关逻辑。
在 `FileReceiver.cs` 中确保在 UI 线程上更新接收状态。
