[feat] negodata: 견적 목표가 산정 개편 + 협상 초청메일 + 카드 사용구분

[견적·목표가] - 목표가 산정 KTC 기준 정비(MD 우선, 없으면 인터넷최저가·매입가·판매가 중 최저 / 신규는 인터넷최저가만) - 인터넷 평균 수수료 0.078 상수화(견적설정 컬럼 제거) - 앵커링가 세션 저장 + 목표가 클릭 시 산정내역 모달 - 재생성 시 목표가·앵커링가 재계산 없이 직전 값 상속(KTC) - MD 제시가·협력사 유형(유통·제조·총판·기타) 입력 [협상카드] - 사용 구분(공통/신규견적전용/재견적전용) [협상 진행] - 협력사 초청 메일 발송(일괄/개별·재발송, 발송상태 표시) [기타] - 견적상세 창 닫기 버그 수정, 불필요한 컬럼 주석 정리 - DB: 기존 DB는 postgres-init/04-alter.sql 적용 필요(자동 마이그레이션 없음) Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
