refactor: 全面代码重构与项目结构整理

安全性:
- 所有SQL查询改用参数化查询(db_query)，防止SQL注入
- TUSHARE_API_TOKEN集中到config.php常量，移除硬编码和多份拷贝
- getBasic.inc.php中$_REQUEST输出到JS时添加htmlspecialchars转义

代码组织:
- 21个页面文件移至charts/子目录，根目录仅保留入口文件
- ajax.inc.php拆分：esfTradeDaily/esfListDaily迁至getEstate.inc.php
- getBasic.inc.php拆分：HTML组件函数迁至新建的widgets.inc.php
- 前端依赖去重：移除lib/echarts.min.js、libai/3.4.16.js、research/js/3.4.16.js

规范化:
- AJAX响应格式统一为jsonResponse()标准封装
- 前端全局变量统一为window.chartConfig对象模式
- 修复PHP 8.4 Deprecated警告(getEstateData、getStockHistoryDataByTS参数顺序)
- html/head.php中jQuery/CSS路径改为绝对路径，修复charts/子目录加载问题
