chore(build, dependencies): add Room support with KSP integration and optimize testing dependencies

- Integrated Room plugin and runtime dependencies into `local-db` module, including schema configuration for Room.
- Added KSP processor dependencies for Kotlin Multiplatform compatibility.
- Enhanced `core-domain` module by refining and temporarily adjusting testing dependencies for resolution issues.
