Subject: [PATCH] fix: resolve CS1574 unresolved DatabaseFacade/ChangeTracker
 doc crefs in sample DbContexts (#539)

Adds the missing using Microsoft.EntityFrameworkCore.Infrastructure (and
.ChangeTracking where needed) directives so XML doc <see cref=.../> tags
referencing DatabaseFacade.EnsureCreated(Async) and ChangeTracker.Clear
resolve correctly, matching the existing pattern in TodoApp.Avalonia.

Affected sample DbContexts:
- TodoApp.Uno/Database/AppDbContext.cs
- TodoApp.WPF/Database/AppDbContext.cs
- TodoApp.WinUI3/Database/AppDbContext.cs
- TodoApp.BlazorWasm.Server/Database/TodoContext.cs
