feat(expansion): GUARDiA v3 — 6 P1 routers + 7 DB tables

라우터 (584개 엔드포인트, 신규 39개):
- rag_engine.py: 하이브리드 RAG 검색 (BM25+pgvector+RRF) + Ollama 답변
- jira_sync.py: Jira 양방향 SR 동기화 + 웹훅 수신
- kpi_engine.py: KPI 정의·계산·신호등 + 내장 5개 템플릿
- tenant_portal.py: 테넌트 셀프서비스 포털 + 사용자 초대
- bi_dashboard.py: BI 대시보드 (트렌드·히트맵·퍼널·MTTR)
- autonomous_workflow.py: 조건 기반 자율 워크플로우 엔진

DB 모델 (7개 신규 테이블):
tb_rag_feedback, tb_jira_config, tb_jira_sync_mapping,
tb_kpi_definition, tb_kpi_value,
tb_auto_workflow_rule, tb_auto_workflow_run
