Initial commit: Plan B Logistics Flutter app with dark mode and responsive design

Implements complete refactor of Ionic Angular logistics app to Flutter/Dart with:
- Svrnty dark mode console theme (Material Design 3)
- Responsive layouts (mobile, tablet, desktop) following FRONTEND standards
- CQRS API integration with Result<T> error handling
- OAuth2/OIDC authentication support (mocked for initial testing)
- Delivery route and delivery management features
- Multi-language support (EN/FR) with i18n
- Native integrations (camera, phone calls, maps)
- Strict typing throughout codebase
- Mock data for UI testing without backend

Follows all FRONTEND style guides, design patterns, and conventions.
App is running in dark mode and fully responsive across all device sizes.
