Append English names to language picker

Add an englishDisplayName computed property to AppLanguage that returns English labels for each case. Update SettingsView to display the localized name plus the English name (e.g. "Localized (English)") in the language picker. Add unit test testEnglishDisplayNameMapping_forPickerLabels to verify the englishDisplayName values. This improves clarity by showing English labels alongside localized names in the picker.
