Description

This pull request includes changes to the Weather.razor component in the Blazor application to handle potential null values and initialize arrays properly.

Improvements and code safety enhancements:

• tests/DevApps/blazor/BlazorApp/Components/Pages/Weather.razor: Modified the user identity display to use null-conditional operators to prevent potential null reference exceptions.
• tests/DevApps/blazor/BlazorApp/Components/Pages/Weather.razor: Initialized the forecasts array to an empty array using Array.Empty<WeatherForecast>() to avoid null-related issues.

Fixes #3265
