Overview

Replace System.Drawing.Imaging usage in ImageMerger.xaml.cs with SkiaSharp or SixLabors.ImageSharp (both already referenced in the project).

Files Affected

• FModel/Views/ImageMerger.xaml.cs

Findings

• Uses System.Drawing.Imaging.ImageFormat for TIF → PNG conversion via GDI+
• System.Drawing.Common is unsupported on Linux in .NET 6+; throws PlatformNotSupportedException
• Both SkiaSharp and SixLabors.ImageSharp are already referenced in the project and support TIF decoding and PNG encoding

Acceptance Criteria

• Image merge produces a valid PNG on Linux
• No System.Drawing references remain in ImageMerger.xaml.cs
