AI관리 시스템 교체: ai-assistant 제거 + 멀티 에이전트 오케스트레이션 이식

Epic A: ai-assistant 디렉토리/Spring 프록시/프론트엔드 메뉴 완전 제거
Epic B: Flyway 도입 + 13 신규 테이블 마이그레이션
Epic C: 9 서비스 + 7 컨트롤러 + LlmClient 추상화 (Java 21/Spring/MyBatis)
Epic D: ApiKey 인증 필터 (sk-pipe-* 키 SHA-256 검증)
Epic E: OpenClaw 외부 엔진 docker-compose 통합
Epic F: Next.js 7 페이지 + lib/api/aiAgent.ts 이식
Epic G: 화면 그룹/메뉴 등록 마이그레이션 (V014)
Epic H: 통합 빌드 검증

- DB: invyone PostgreSQL에 ai_agents/ai_agent_groups/... 13 테이블 + Quartz
- 멀티테넌시: 모든 테이블에 company_code 강제 필터
- LLM: Anthropic/OpenAI/Google/Ollama 직접 클라이언트 (Spring AI 미도입)
- 스케줄러: Quartz JDBC JobStore (cron 기반)
