fix(cli): verify 명령 ImportError 핫픽스 — make_broker→_build_broker

운영 배포 스모크(REL-010 STEP2)서 trex-core verify가 ImportError(make_broker 부재)로 실패.
_cmd_verify가 존재하지 않는 trex_core.adapters.broker.make_broker를 import하던 것을
_cmd_sync와 동일한 trex_core.runtime.daemon._build_broker로 교체. 회귀 테스트 2개 추가.
747 passed/회귀 0. CLI 전용, trading/wire 무관.
