This PR implements full internationalization (i18n) support for OrionHealth, covering the top 20 most spoken languages globally.

Key changes:

  1. ARB Files: 20 language files created in lib/l10n/ containing translations for core UI components.
  2. Infrastructure: Configured l10n.yaml and pubspec.yaml to support automated generation of localization classes.
  3. UI Integration:
    • lib/main.dart: Updated to use AppLocalizations.localizationsDelegates and supportedLocales. Removed the forced 'es' locale.
    • lib/features/user_profile/presentation/pages/user_profile_page.dart: Fully localized all personal info, app preferences, and privacy settings.
    • lib/features/reports/presentation/pages/reports_page.dart: Localized the app bar title.
  4. Verification:
    • Ensured RTL support for languages like Arabic and Urdu.
    • Added test/l10n_integration_test.dart which successfully verifies 'es', 'fr', and 'ar' translations.
    • Confirmed flutter gen-l10n correctly updates the generated Dart classes in lib/l10n/.

This setup allows OrionHealth to reach a global audience while maintaining a single source of truth for UI strings.

Fixes #240

Code Review

This pull request implements internationalization (i18n) support for the application, covering approximately 20 languages. It introduces ARB files, configures the Flutter localization generator, and replaces hardcoded strings with localized keys across the reports and user profile pages. Feedback focuses on best practices for generated files, ensuring consistency across all translation files, localizing remaining hardcoded strings (like "Dark Mode" and dates), and correcting a label-icon mismatch in the main navigation.

Generated localization files (including app_localizations.dart and the language-specific implementations) are included in this pull request. When generate: true is configured in pubspec.yaml, these files are typically excluded from version control (via .gitignore) to avoid redundancy, unnecessary diff noise, and potential merge conflicts. Since they are automatically recreated during the build process, it is recommended to remove them from the repository.

This ARB file (along with several others like app_fr.arb, app_hi.arb, etc.) is missing 14 translation keys that are present in the template app_en.arb (e.g., error, loading, profileSaved, changePassword). This inconsistency results in the application falling back to English for these UI elements in those locales, which contradicts the PR's objective of providing full internationalization support for the top 20 languages.

The subtitle 'Dark Mode' is hardcoded in English. To maintain consistency with the internationalization efforts in this PR, this string should be moved to the ARB files and accessed via AppLocalizations.

The date '15 de Agosto, 1988' is hardcoded in Spanish. For a fully localized application, dates should be formatted dynamically using the intl package's DateFormat class, which automatically respects the current locale's conventions (e.g., 'August 15' vs '15 de agosto').

There is a mismatch between the navigation icon and its new localized label. The icon Icons.calendar_month_outlined (previously labeled 'Citas' or Appointments) is now using the reports key, which translates to 'Reports'. This is confusing for users as a calendar icon typically represents schedules or appointments, not health reports. If the intention was to localize the existing 'Appointments' tab, a dedicated appointments key should be used instead.
