feat(expansion): GUARDiA v3 P3 완성 — 13 routers + 14 DB tables

라우터 (667개 엔드포인트, P3 신규 69개):
- multimodal.py:      llava 이미지 분석 + 에러 자동 분류
- learning_loop.py:   Ollama 파인튜닝 + 품질 지표
- ai_insights.py:     주간 인사이트 + 반복 패턴 + 개선 권고
- container_alerts.py: Docker 이상 감지 → SR 자동 생성
- ncloud.py:          NCloud API (서버/LB/스토리지/비용)
- billing.py:         구독 플랜 + 사용량 측정 + 청구서
- servicenow.py:      ServiceNow CMDB/Incident 양방향 연동
- erp_connector.py:   그룹웨어/HR ERP 연동 + 결재 웹훅
- kakao_notify.py:    카카오 알림톡 + 대량 발송
- auto_report.py:     Excel/PDF 보고서 자동 생성·다운로드
- benchmark.py:       기관 간 익명 벤치마킹 (완전 익명화)
- cohort_analysis.py: 도입 코호트 + 리텐션 + 기능 도입률

DB 모델 (14개 신규 테이블):
tb_learning_run, tb_container_alert_{rule,log},
tb_ncloud_config, tb_subscription, tb_invoice,
tb_servicenow_{config,mapping}, tb_erp_config,
tb_kakao_{config,notify_log}, tb_report_{record,schedule},
tb_benchmark_contrib
