fix(P0): 杜邦分析接口去除硬编码错误数据 — equity 114万→358.4万、ROE 12.38%→3.95%、新增hanke分支读DB(KPI 2026H1 verified)

- 新增 _get_dupont_kpi 辅助函数: 按 entity_id+kpi_code 查 kpi_definitions→kpi_values(period=2026H1, verified)
- bohai: 净权益修正为358.4万(来源 bohai_comprehensive_analysis_2026.md 试算平衡表)，财务杠杆4.68x→1.49x，负债率78.6%→32.8%结构健康，ROE≈3.94%，删除误导性加杠杆建议
- hanke: 新增分支，从DB读 F_REVENUE=713.27/F_NET_PROFIT=-90.86，净利率-12.74%，资产/权益缺失时factor返回null标注数据待补充，prev_roe返回null(前端兼容显示无对比)，接口返回200
