## Detailed Description of the Pull Request / Additional comments

Added validation guard in `ImageSize.Name` property setter:

```csharp
public string Name
{
    get => _name;
    set
    {
        if (!string.IsNullOrWhiteSpace(value))
        {
            SetProperty(ref _name, value);
        }
    }
}
```

Invalid assignments (empty, null, whitespace) are silently ignored,
preserving the existing value. This matches the existing pattern used
for `FileName` validation in `ImageResizerViewModel`.

TwoWay binding in UI causes the TextBox to revert when users attempt to
clear the field—standard behavior for required fields.

## Validation Steps Performed

- Added unit test `ImageSizeNameShouldNotBeSetToEmptyOrNull()` covering
all rejection and acceptance cases
- Verified silent rejection behavior matches `FileName` property pattern

> **Detailed description:**
> While users edit an image size in the ImageResizer settings on PT's
settings ux they are able to clear the name of the image size. This
doesn't lead to errors/exceptions, but it also doesn't make sense to
have sizes without a name. So we should prevent user from doing this in
the edit dialog.
> 
> _**Note:**_
> This is the second and last change that is needed to prevent the users
from having incorrect image size settings (#8698). But I think this is
not as relevant, because a missing name won't break image resizing._
