[BUG] <When using VictoriaMetrics time series library, springboot2 monitoring does not display the key correctly when displaying multi-record charts>

### Is there an existing issue for this?

- [X] I have searched the existing issues

### Current Behavior

查看内存使用图表时,其key为空
---
hzb error日志有错误(不确定是否有关联性)

### Expected Behavior

应根据内存监控中space列来显示图表

### Steps To Reproduce

1. 使用VictoriaMetrics
2. 运行hzb
3. 添加springboot2监控
4. 等待数据
5. 查看历史图表

### Environment

```markdown
HertzBeat version(s): v1.4.4
---
系统信息:
版本 Windows Server 2022 Datacenter
版本号 21H2
操作系统内部版本 20348.2159

### Anything else?

_No response_

Start with warehouse/store/HistoryVictoriaMetricsDataStorage.java at lines 181 and 189, then inspect DataStorageDispatch and reproduce the VictoriaMetrics springboot2 monitoring workflow described in the issue. Determine why the memory chart key is empty and verify that multi-record charts display the memory monitor's space value; separate this from the reported connection error.
