Class MessageBox

Static convenience helpers that build a small content tree and show it via Dialog<TResult> - a message with a button row (ShowAsync(Canvas, string, DialogButtons)), or a single-line text prompt (ShowInputAsync(Canvas, string, string?)). A separate, non-generic class rather than static members on Dialog<TResult> itself, to avoid declaring statics on a generic type (CA1000) while keeping Dialog<TResult>'s own API fully type-safe.
