性能与用户体验全面优化
前端性能:
- 移除 Three.js 依赖（~600KB），天气粒子改为纯 CSS 动画 + Canvas 2D
- Google Fonts 切换为 next/font 自托管，消除跨域字体请求
- 合并 ScanTerminalLightTheme.module.css (37KB) 到主 CSS，亮/暗主题统一用 CSS 变量
- 新增 /api/dashboard/init 聚合端点，首次加载 4 次往返 → 1 次
- 添加 Service Worker 静态资源缓存，修复 PWA manifest 配置
用户体验:
- 新增全局错误边界 error.tsx / global-error.tsx，崩溃不再白屏
- 决策卡和城市详情的更新时间改为相对时间（"15秒前"），每秒自动刷新
- 数据陈旧时状态标签从青色切换为琥珀色提示
DEB 算法增强:
- 市场扫描路径接入 Open-Meteo 多模型数据（ECMWF/GFS/ICON/JMA/HRDPS 等）
- MAE 计算加入时间衰减（decay_factor=0.85），近期模型误差权重更高
Scope-risk: MEDIUM — 全量 170 测试通过，前端 TypeScript/build 通过，ruff 零告警
Tested: python -m pytest -q (170 passed), npx tsc --noEmit (0 errors), npm run build (success), ruff check .
