Improve error handling and reformat XAML for clarity

- Added `using System.IO;` to `SpotifyWebClient.cs`.
- Enhanced `JsonException` handling in `SpotifyWebClient.cs` to write response content to `data.json` if it does not exist.
- Reformatted `HistoryWindow.xaml` for better readability:
  - Adjusted indentation and line breaks.
  - Changed the order of attributes.
  - Ensured attributes are on separate lines.
  - Replaced `PackIconFontAwesome` with `PackIconMaterial` for the refresh button.
  - Made minor adjustments to `DataGrid` and `ListBox` elements.
