fix(trade-monitor): sell_climax holdings_intel 정합

BE 회신(holdings_intel.py:109-118)에 맞춰 반전 기준을
price<day_open → price<day_high×climax_close_pct(윗꼬리)로 변경.
- kis_client.get_quote에 day_high(stck_hgpr) 추가
- monitor._build_ctx가 day_high를 ctx로 전달
- climax_vol_x·climax_close_pct를 monitor-set exit_params에서 읽기
  (fallback: TM_CLIMAX_VOL_MULT/0.97)
- 테스트 36/36 (climax exit_params 2건 추가)
