refactor(ForecastReport): 架构优化与性能提升

Browse Source 
阶段一 - 核心优化:
- 所有子组件添加 React.memo 防止不必要重渲染
- 图表组件统一使用 EChartsWrapper 替代 ReactECharts
- 提取 isForecastYear、IMPORTANT_METRICS 到 constants.ts
- DetailTable 样式提取为 DETAIL_TABLE_STYLES 常量

阶段二 - 架构优化:
- 新增 hooks/useForecastData.ts：数据获取 + Map 缓存 + AbortController
- 新增 services/forecastService.ts：API 封装层
- 新增 utils/chartFormatters.ts：图表格式化工具函数
- 主组件精简：79行 → 63行，添加错误处理和重试功能

优化效果:
- 消除 4 处 isForecastYear 重复定义
- 样式从每次渲染重建改为常量复用
- 添加请求缓存，避免频繁切换时重复请求
