- Removed unused import in `BackendArchitectureTest.kt` and improved clarity of comments on service module dependencies.
- Added a TODO placeholder in `DeepLinkHandler.kt` for upcoming deep link processing implementation.
- Replaced `initKoin` with `startKoin` for DI initialization consistency across platforms.
- Introduced `StateNavigationPort` with `StateFlow` to streamline navigation state management.
- Migrated `AppScreen` to sealed class with route mapping for better navigation handling.
- Deleted unused `frontend/shared` module and removed related dependencies from build files.
- Cleaned up legacy navigation and Redux-related code, aligning with MVVM architecture.
Integrated a new `:platform:architecture-tests` module using ArchUnit to enforce backend and frontend architecture rules. Configured explicit dependencies to all relevant modules and implemented rules to prevent cross-dependencies between backend services and frontend features. Replaced legacy Gradle-based architecture guards with this robust solution. Updated CI pipeline to include these tests.
