feat(l10n): 국제화(L10n) 시스템 도입 및 하드코딩 텍스트 변환

- flutter_localizations 및 intl 패키지 추가
- l10n.yaml 설정 파일 및 app_ko.arb 메시지 파일 생성
- 모든 화면(app, front, game_play, new_character, save_picker)의 하드코딩 텍스트를 L10n 키로 변환
- 테스트 파일에 localizationsDelegates 추가하여 L10n 지원

+/// Callers can lookup localized strings with an instance of L10n
+/// returned by `L10n.of(context)`.
+///
+/// Applications need to include `L10n.delegate()` in their app's
+/// `localizationDelegates` list, and the locales they support in the app's
+/// `supportedLocales` list. For example:
+///
+/// ```dart

+/// ## Update pubspec.yaml
+///
+/// Please make sure to update your pubspec.yaml to include the following

+///
+/// ```yaml

+///   # Internationalization support.
+///   flutter_localizations:

+/// Editor menu, then select Localizations from the pop-up menu.
+///
+/// Select and expand the newly-created Localizations item then, for each
