Deleted obsolete files and models from the `ping-feature` module, including redundant enums, the old `PingApiClient`, and legacy view models. Simplified the module by consolidating its implementation with the new Koin-based DI and shared client architecture. Cleaned up unused code and improved module maintainability.
Injected `PingViewModel` via Koin to align with dependency injection best practices. Suppressed Gradle deprecation warnings and added the `frontend.core.sync` dependency. Cleaned up outdated packages in `yarn.lock`.
Migrated CORS settings from code to `application.yaml` for better separation of concerns. Integrated `ping-api` into the new `contracts` module for improved modularity. Updated Gradle scripts and dependencies accordingly to reflect the new project structure.
