[Enhancement]: HiDPI support

[LoganDark]

Describe the new feature or enhancement

UnityExplorer is very small on my display:

It would be helpful if it could be scaled up in the options (I have a 200% scale factor, for example).

Run this in the C# console or to your startup.cs

UnityExplorer.UI.UIManager.UICanvas.scaleFactor = 1.8f;
