/**
 * Shared mock for react-i18next
 *
 * Jest automatically uses this mock when react-i18next is imported in tests.
 * The default behavior returns the translation key as-is, which is suitable
 * for most test scenarios.
 *
 * For tests that need custom translations, you can override with jest.mock():
 *
 * @example
 * jest.mock('react-i18next', () => ({
 *   useTranslation: () => ({
 *     t: (key: string) => {
 *       if (key === 'some.key') return 'Custom translation'
 *       return key
 *     },
 *   }),
 * }))
