fix(framework):修复异常处理和日期转换中的线程安全问题

- 移除 BadRequestException 中不必要的构造函数注释
- 在 ExecutionTimeStatisticsFaceAspect 中使用 error 级别记录异常日志
- 将 DateStringArraysToListDateConverter 和 DateStringToDateConverter 中的 SimpleDateFormat 改为 ThreadLocal以确保线程安全
- 简化 CsWsServer 中 stopTask 方法的异常处理逻辑
- 修正 CsFileUtil 中时间格式化字符串，将小写 hh 改为大写 HH 以正确表示24小时制
