멀티모듈 인프라: schema.d/ 분리 + acq.fd 범용필드 (병렬 팬아웃 충돌회피)

- db/schema.sql → db/schema.d/00-base.sql, compose가 schema.d 디렉터리 마운트
  (모듈들이 db/schema.d/NN-<mod>.sql 로 disjoint 추가)
- acq.fd에 범용 스크래치필드(T_ARG/T_STR/T_AMT/T_KEY/T_ID) → 모듈이 acq.fd 미수정
- setapp.sh gitignore 제외(필수 런타임 config)
- 검증: 4서버 runok, 41서비스, 체인 커밋 유지
