refactor: use project properties for internal dependencies

- Replace hardcoded JUnit Jupiter version with property reference
- Use project properties for group ID and version in internal dependencies
- Replace hardcoded group ID with ${project.groupId}
- Replace hardcoded version with ${project.version}

This improves maintainability by avoiding duplicated version information.
