改进错误处理：避免异常被静默吞掉

- FileUtils.imageToBase64ByStream 读取失败时抛出 WxRuntimeException，不再 printStackTrace 后返回 null
- AesUtils.HMACSHA256 签名计算失败时抛出 WxRuntimeException，不再返回 null 导致签名为空
- RequestUtils.readData 读取回调请求体失败时抛出异常，不再静默返回不完整内容
- PartnerTransferServiceImpl.spDayEndBalance 传播查询异常，不再返回 null
- WxMpMemberCardServiceImpl.getActivatePluginParam 解析失败时抛出 WxErrorException
- DefaultApacheHttpClientBuilder 空闲连接监控线程被中断时恢复中断标志
- 支付回调转换器、临时二维码文件删除、payBaseUrl 解析失败改为记录日志

新增 FileUtilsTest、AesUtilsTest 回归测试
