Storage meter

Numbers are somewhat hard to read. But graphics are easier, am I right?

**is your feature request related to a problem? Please describe.**
This is slightly related to a previous suggestion I made (#1358). But basically, there is a video on YouTube that shows html tags that "no one teaches". I mentioned one of those, but in this suggestion, I wanna mention the meter tag.

**Describe the idea / solution you'd like**
So, next to the actual numbers for the storage, I was thinking of including the meter tag, and have some js to handle it. I don't really know if it supports the low argument to be percentages (Like 25% being 10 of 40), of if it can be higher than the high or optimal arguments... But it could be a nice addition. The video in question is [https://www.youtube.com/watch?v=VkWJQe_EsjQ&t=362s](url)

**Describe any alternatives you've considered**
Honestly, just not including it. Or use the progress tag instead, which is also shown in that video.

**Additional context**
None at all

查找显示存储数值的前端代码，可能位于模板或 JavaScript 文件中。查找现有的用于显示存储信息的 UI 组件。任务是将 或 标签添加到数值旁边。检查后端是否以适用于 meter 的 min、max、low、high 和 optimal 属性的格式提供存储数据。测试视觉集成，并确保存储发生变化时 JavaScript 能正确更新 meter。
