feat(theme): 亮色主题基础设施 + 全部图表主题化

- lib/theme.ts: localStorage 持久化 + useTheme hook (本页/跨标签页同步) + ChartTheme 图表调色板 (ECharts/lightweight-charts 画布不吃 CSS 变量, 统一从这里取色) - index.html: 去掉写死的 class=dark, 换预渲染内联脚本 (默认暗色, 切过亮色则保持), 避免首屏闪烁 - Layout: 侧边栏底部亮/暗切换按钮 (设置入口上方) - 图表主题化 (切换即时生效, 无需刷新): · EChartsIntraday / EChartsCandlestick / CandlestickChart (lightweight-charts applyOptions) / AnalysisKChart · 回测 4 图 (StrategyNav/FactorIC/FactorGroupNav/ReturnDistribution) · Sentiment 页双图序列颜色 (红涨绿跌/MA线) 双主题通用保持不变; 轴/网格/十字线/ tooltip/信息栏背景按主题切换 CSS 变量亮色板 index.css 里本就有 (:root), 首次真正启用
