Fixed the `NullReferenceException`. The XAML-named controls weren't available as fields, so I updated the code to use `FindControl<T>()` to locate them.
**Changes made:**
- Updated `SetupEventHandlers()` to use `FindControl<T>()` for all button and control references
- Updated all event handlers that access `WorkersGrid` and `WorkerTypeTabs` to use `FindControl<T>()`
The build succeeded. Run `dotnet run` again; the window should appear. The application was crashing during initialization because it tried to access controls that weren't initialized yet. Using `FindControl<T>()` ensures the controls are found after the XAML is loaded.

Excellent! When I click add worker, it closes.

The same issue: `WorkerEditWindow` accesses named controls directly. Updating it to use `FindControl<T>()`:
