refactor(search): Phase 2A/2B cand reranker 잔재 teardown

- RERANKER_BACKEND_MAP 에서 cand_gte_ml_base 슬러그 제거 (컨테이너·DB 테이블 마이그360·override 이미 종료)
- docker-compose.override.cand.yml / override.rerank-cand.yml 삭제
- search.py allowlist · run_eval.py help 정합
- dispatcher scaffold(_resolve_reranker)는 보존 (후보 재진입 대비)
