Phase 2c-1: ac 모듈 per-service 분해 (1서비스=1파일+카피북) + build.sh 이중스타일

- app/src/ac/svc/: 30 서비스 .pgc + 31 카피북 .h (각 typedef struct + prototype)
- ac_svr.pgc = 얇은 디스패처(advertise 테이블만)
- build.sh: src/<mod>/svc/*.pgc → lib<mod>svc.a 링크, inline/split 자동판별
- ac dbio 25 + batch 17 + run 17 스크립트
- 고유도: svc 30/30, dbio 25/25 (정규화 md5, 클론 0)
- 검증: 12서버 runok, 333 서비스, 매입체인 XA 커밋, prepared_xacts=0
