feat: 预测性成本智能模块上线(IMA 2026.7前沿) — 接线+重建页面

- CostIntelligence.vue 重建(被清理的未提交文件): 模型选择(线性/移动平均)+预测期数+统计卡+KPI表格+趋势图
- 路由: /cost-intelligence(挂财务维度D执行与控制), 修正 predict/cost-intelligence 路径不匹配
- 菜单: 预测性成本智能(ceo/finance/it)
- 后端API已存在: /predict/kpi-forecast/finance (kpi_forecast_engine)
- 验证: Chrome实测 5 KPI预测(厂补率/营收/净利/费用率/毛利), 趋势图渲染, pytest不影响
- 注: 置信度诚实标注(全部low=历史数据波动大, MVP原则)
