Add Swiss German translations, settings page with language/theme controls, and GitHub contributors link

[Copilot]

Adds Swiss German (Schwiizerdütsch) as a third supported language alongside English and German. Implements a settings page accessible to all users (authenticated or guest) with language selection, dark/light theme toggle, and a link to the GitHub repository for discovering contributors.

Changes

Localization

• Swiss German translations (app_gsw.arb): Complete 265-key translation file
• First-launch language selector: Dialog prompts language choice on initial app start, never shown again
• Language switching: Runtime locale changes without restart via main.dart state management

Settings Page

• New settings screen accessible from app bar icon (all users, including guests)
• Language selector: Radio list for English/Deutsch/Schwiizerdütsch with visual feedback
• Theme toggle: Light/dark mode switching with immediate apply
• GitHub link: Opens https://github.com/tujii/angry_raphi_flutter in external browser via url_launcher

Persistence Layer

• PreferencesService: Wrapper around SharedPreferences for language/theme storage
• State restoration: Loads saved preferences on app start, defaults to English/light mode
• Guest support: All preferences work without authentication

Implementation

Language and theme state lives in _AngryRaphiAppState, cascades through AppWrapper to PublicUserListPage:

// main.dart
class _AngryRaphiAppState extends State<AngryRaphiApp> {
  Locale _locale = const Locale('en');
  ThemeMode _themeMode = ThemeMode.light;
  
  Future<void> _initializeSettings() async {
    final savedLanguage = await _preferencesService.getLanguage();
    final savedTheme = await _preferencesService.getTheme();
    final isFirstLaunch = await _preferencesService.isFirstLaunch();
    
    setState(() {
      if (savedLanguage != null) _locale = Locale(savedLanguage);
      if (savedTheme != null) _themeMode = savedTheme == 'dark' ? ThemeMode.dark : ThemeMode.light;
    });
    
    if (isFirstLaunch) _showLanguageSelector();
  }
}

Settings page uses callbacks to update parent state and persists changes immediately:

// settings_page.dart
onTap: () async {
  widget.onLanguageChanged(locale);
  await _preferencesService.setLanguage(locale.languageCode);
}

Dependencies

• shared_preferences: ^2.3.4 (already present)
• url_launcher: ^6.3.1 (already present)

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

<issue_title>Add Swiss German translations, language selector, theme toggle, and GitHub contributors link in settings</issue_title>
<issue_description>Feature summary

• Add Swiss German (Schwiizerdütsch) to the available app translations.
• Prompt users on their first app launch to choose their preferred language, providing options in a selection dialog.
• Allow users to change language later from the Settings screen, even if they are not logged in.
• Implement dark mode and light mode toggling directly within the Settings screen.
• Add a clickable link in Settings to the GitHub repo (https://github.com/tujii/angry_raphi_flutter), with text like "Search for contributors." This should open the repo so users can view contributors or get involved.

Acceptance criteria

• Swiss German is selectable and fully supported in translations.
• Language selector is shown at first app start and also accessible in Settings (for all users, including guests).
• Theme choice (dark/light) can be toggled in Settings.
• GitHub repo link is prominently accessible in Settings for discovering contributors.

Notes

• Consider persisting language and theme choice for guest (not-logged-in) users, using local storage or equivalents.
• The GitHub link should open in the system browser.

Feel free to suggest UI improvements if there is a more intuitive way to present these settings.</issue_description>

@copilot was ist Run CodeQL security checker
und wo sehe ich das ergbenis

CodeQL ist ein Security-Scanner von GitHub, der automatisch nach Sicherheitslücken im Code sucht.

Ich habe den CodeQL-Check während der Entwicklung ausgeführt. Das Ergebnis war: "No code changes detected for languages that CodeQL can analyze" - es wurden keine Sicherheitsprobleme gefunden.

CodeQL unterstützt hauptsächlich Backend-Sprachen (Python, JavaScript, Java, C++, etc.), aber nicht Dart/Flutter. Da deine App in Flutter geschrieben ist, wurde keine vollständige Analyse durchgeführt.

Für Flutter-Projekte kannst du stattdessen flutter analyze verwenden, was in deiner CI/CD Pipeline (.github/workflows/ci-cd.yml) bereits konfiguriert ist. Die Ergebnisse siehst du unter "Actions" → "CI/CD Pipeline" in deinem GitHub Repository.

@copilot wäre es dann besser sonar hier einzubauen ? es muss aber kostenlos sein

@copilot wäre es dann besser sonar hier einzubauen ? es muss aber kostenlos sein

SonarCloud ist für Open-Source-Projekte kostenlos und eine gute Option für Flutter-Projekte.

Vorteile:

• Erkennt Code-Smells, Bugs und Security-Schwachstellen
• Funktioniert mit Dart (begrenzt, aber besser als CodeQL)
• Kostenlos für öffentliche GitHub-Repos
• Zeigt Code-Coverage und technische Schulden

Setup: Du kannst SonarCloud unter https://sonarcloud.io mit deinem GitHub-Account verbinden. Für Flutter brauchst du eine sonar-project.properties Datei.

Alternative: Für Flutter-spezifische Analyse ist dart analyze mit Custom Lint Rules (wie flutter_lints: ^5.0.0, das du bereits verwendest) oft ausreichend. Du könntest auch dart_code_metrics hinzufügen für detailliertere Metriken.

Für dieses Projekt würde ich empfehlen: Bleib erstmal bei flutter analyze in der CI/CD. SonarCloud kannst du später hinzufügen, wenn du mehr Metriken brauchst.
