fix: 세션14 미커밋 개선사항 일괄 처리

- inject_computed_harness.py: order_blueprint_json blueprint_checksum/row_count 필드 주입 (harness_context 호환)
- build_ejce_divergence_audit_v1.py: no_data 시 gate FAIL → WARN (DAG 진행 차단 방지)
- harness_coverage_auditor.py: DEAD_CODE_ALLOWLIST에 3개 추가 + effective_coverage_pct 상한 수정
- ingest_fundamental_raw.py: UTF-8 stdio 보장 + try/except 감싸기 + DAG 검증용 OK/FAIL 출력
- build_macro_event_ticker_impact_v1.py: MACRO_EVENT_TICKER_IMPACT_V1 신규 구현
