添加临时文件清理异常处理和修改大纲接口为POST方法

- 在analyze_markdown、analyze_markdown_stream和get_markdown_outline函数中添加了
  try-catch块来处理临时文件清理过程中的异常
- 将/analyze/md/outline接口从GET方法改为POST方法以支持文件上传
- 确保在所有情况下都能正确清理临时文件，并记录清理失败的日志

refactor(health): 改进健康检查逻辑验证实际数据库连接

- 修改MySQL健康检查，实际执行SELECT 1查询来验证连接
- 修改MongoDB健康检查，执行ping命令来验证连接
- 修改Redis健康检查，执行ping命令来验证连接
- 添加异常捕获并记录具体的错误日志

refactor(upload): 使用os.path.basename优化文件名提取

- 替换手动字符串分割为os.path.basename来获取文件名
- 统一Excel上传和导出中文件名的处理方式

feat(instruction): 新增指令执行框架模块

- 创建instruction包包含意图解析和指令执行的基础架构
- 添加IntentParser和InstructionExecutor抽象基类
- 提供默认实现但标记为未完成，为未来功能扩展做准备

refactor(frontend): 调整AuthContext导入路径并移除重复文件

- 将AuthContext从src/context移动到src/contexts目录
- 更新App.tsx和RouteGuard.tsx中的导入路径
- 移除旧的AuthContext.tsx文件

fix(backend-api): 修复AI分析API的HTTP方法错误

 {source_info}
 
-请生成5-10个简洁的表头字段名，这些字段应该：
-1. 简洁明了，易于理解
-2. 适合作为表格列标题
-3. 直接对应源文档中的关键数据项
-4. 字段之间有明显的区分度
+【重要要求】
+1. 请仔细阅读上面的源文档表格，找出所有不同的列名（如"产品名称"、"1995年产量"、"按资产总额计算(%)"等）
+2. 直接使用这些实际的列名作为表头字段名，不要生成新的或同义词
+3. 如果一个源文档有多个表格，请为每个表格选择合适的列名
+4. 生成3-8个表头字段，优先选择数据量大的表格的列
