WBS-7.3: GAS→Python 마이그레이션 5개 항목 완료 (F14, F02-F06)

- F14: late_chase_risk_score 검증
  * GAS가 유일한 생산처 (Python canonical 없음)
  * migration_action: KEEP_IN_GAS로 정정, status: DONE

- F02/F03/F04/F06: priceBasis 로직 포팅
  * formulas/price_basis_v1.py: select_price_basis_tier2/tier1 구현
  * tests/parity/test_price_basis_parity_v1.py: 8 parity 테스트 (모두 PASS)
  * GAS Number.isFinite() 의미론 정확히 재현 (math.isfinite 사용)
  * 모든 테스트 112/112 PASS

남은 작업 (4개):
- F05: decision_logic (action assignment)
- F07: score_logic (threshold addition)
- F10: routing decision
- F15: late_chase_gate
