Enable better precision for memory sizes

Options:
1. Button that switch from rough units to bytes
2. We can show consistent units rather than mixing KB and MB on different lines. That way it's easier to visually compare. I could also see there being buttons for Bytes, KB, MB, GB (similar to the proposal for chart display options) to change quickly between them. - Mindy

未指定文件或测试。首先定位 issue 中提到的现有内存大小显示和图表显示选项，然后明确需要哪种单位切换行为。完成的标准是内存值可以一致地进行比较，并且在选择后可以转换为 bytes、KB、MB 或 GB。
