/**
 * HasTranslatableSeeder Trait 단위 테스트.
 *
 * 검증 시나리오:
 *  1. 확장 식별자가 있을 때 필터명이 `seed.{ext}.{entity}.translations` 로 조립됨
 *  2. 확장 식별자가 빈 문자열일 때 필터명이 `seed.{entity}.translations` 로 조립됨
 *  3. 등록된 필터가 없으면 getDefaults() 결과가 그대로 반환됨
 *  4. 등록된 필터가 있으면 활성 lang pack 키가 머지된 결과가 반환됨
 *  5. 매칭 키 (code/slug/key) 가 entry 보강 시 사용되는지 — 필터 콜백 인자로 정확히 전달됨
