test: Refactor test utilities

- Add `test-utils` module to streamline test cases
- Rename module `kotlin-sdk-test` -> `integration-test`
- Move test utilities for managing processes, ports, and TypeScript execution logic
- Make conformance tests work by specifying conformance package version (0.1.8)
