/**
 * Sets up internationalization and translation mocks for testing environments.
 *
 * Mock translations for react-i18next and @trackunit/i18n-library-translation. It creates
 * simple mock implementations that return the key string as the translation, which allows
 * for testing internationalized components without the complexity of actual translations.
 *
 * The mocks support common translation components and hooks like Trans, useTranslation,
 * NamespaceTrans, and useNamespaceTranslation.
 *
 * @example
 * // In your jest setup file
 * import { setupTranslations } from '@trackunit/react-test-setup';
 *
 * setupTranslations();
