- Removed WindowService.cs which was just a thin wrapper around PhotinoBlazor
- Removed WindowOptions, WindowType, and WindowRef models (unused or part of incomplete window tracking)
- Updated Program.cs to directly use PhotinoBlazorAppBuilder
- Service registration now done through direct extension method calls
- Window configuration uses existing extension methods in Startup/Window.cs
- Simplified initialization flow with clearer code structure
- All functionality preserved, just more transparent and maintainable
