fix(frontend): 修复 vendor-charts 循环 chunk 导致的运行时崩溃

## 问题
线上打开首页报错：
vendor-charts-Z9UiCjXy.js: Uncaught ReferenceError:
Cannot access 'd' before initialization

## 根因
T4 bundle 优化把 @ant-design/charts 单独拆为 vendor-charts chunk，但它的深层
@antv/* 依赖图与 vendor chunk 交叉引用，形成 Circular chunk（构建时已有警告
"vendor-charts -> vendor -> vendor-charts"，当时被忽略）。循环 chunk 导致
ES module 求值顺序错乱 → TDZ 错误。

尝试把 @antv 也并入 vendor-charts 仍循环（charts 生态还依赖 lodash/d3 等
公共库，与 vendor 交叉）。

## 修复
移除 vendor-charts 单独拆分，让 @ant-design/charts + @antv 回到 vendor 主 chunk，
消除跨 chunk 循环。保留 vendor-monaco / vendor-antd（构建证明无循环）。
charts 在 Home 首页（默认路由）即需加载，单独拆分的懒加载收益本就微乎其微；
真正的懒加载收益来自 App.tsx 的页面级 React.lazy（保留）。

构建验证：无 Circular chunk 警告，无 vendor-charts chunk。
