feat: P5-W3 본론 완료 — 회계결산/이상치예측/연말명세서 (V74~V78)

P5-W2 원천세·부가세 분기신고 미커밋분 + P5-W3 메뉴/권한 보강(V74) + P5-W3 본론(V75~V78)을 일괄 정리.

- V75 accounting_close / account_balance_snapshot (회계 결산)
- V76 retention_anomaly_alert / forecast_kpi_monthly (이상치·예측 KPI)
- V77 year_end_statement (연말 지급명세서)
- V78 P5-W3 본론 메뉴 4 + 권한 + 공통코드 7그룹 + 테스트데이터
- api: AccountingClose/YearEndStatement/ForecastKpi/RetentionAnomaly Service+Controller
- batch: BatchConfig Step 11/12 (원천세·부가세 분기) 연결
- frontend: 4화면(AccountingClose/YearEndStatement/RetentionAnomaly/ForecastKpi) + API 모듈 4 + 라우트
- frontend: usePermission/PermissionButton EXECUTE 권한 누락 보강
- fix: YearEndStatementMapper.xml 미존재 컬럼 a.agent_code 참조 제거
