Streamlined Keycloak configurations with defaults for development and production in `.env`. Added health checks and improved environment variable documentation with comments to differentiate local and server deployments. Ensured compatibility with pre-built registry images.
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.
