WinUI3 BitmapImage cannot load file:// URIs, so the previous absolute-path fix rendered blank in both themes. Open the themed PNG and decode it via BitmapImage.SetSource instead, which works for installed (release) builds regardless of MRT/PRI resolution.

This pull request improves how splash images are loaded and ensures they are correctly included in published builds. The most important changes are:
Splash image loading improvements:
ApplySplashImage()inMainWindow.xaml.csto load splash images directly from the executable directory, reading the image bytes and decoding from a stream to work around limitations with URI loading and theme qualifiers.Build and deployment fixes:
UniGetUI.csprojto explicitly includeSplashScreen.pngandSplashScreen.theme-dark.pngin the publish output, ensuring the splash image appears in installed (unpackaged) apps.
