Implement migration plan: models, service, MVVM, XAML layout, icons\n\n- Add Models: HistoryItem, VariableItem, FunctionDefinitionItem, IconFont\n- Add Services: ICalculatorService, CalculatorService wrapping interpreter\n- Update MainViewModel: properties and Submit/ToggleFunctions commands\n- Rebuild Views/MainView.axaml with variables, history, input, functions panel\n- Add BoolToGridLengthConverter for panel toggle\n- Wire Material Design Icons font as Avalonia resource in App.axaml/csproj
