### Steps to reproduce

[FormatAsBinaryBytesPerSecString](https://github.com/microsoft/PowerToys/blob/1d11b732b7ba7dbb265d1151531655fd8d83c76d/src/modules/cmdpal/ext/Microsoft.CmdPal.Ext.PerformanceMonitor/PerformanceWidgetsPage.cs#L855) and [FormatAsBytesPerSecString](https://github.com/microsoft/PowerToys/blob/1d11b732b7ba7dbb265d1151531655fd8d83c76d/src/modules/cmdpal/ext/Microsoft.CmdPal.Ext.PerformanceMonitor/PerformanceWidgetsPage.cs#L819) differ only in the unit prefix text (K/M/G vs Ki/Mi/Gi), but both use 1024 as the multiplier.

### ✔️ Expected Behavior

When both methods are present, I'd expect one to use the binary multiplier (1024) and the other to use the decimal multiplier (1000).

Start in src/modules/cmdpal/ext/Microsoft.CmdPal.Ext.PerformanceMonitor/PerformanceWidgetsPage.cs at FormatAsBinaryBytesPerSecString and FormatAsBytesPerSecString. Compare their current multipliers and unit prefixes, then verify that binary units use 1024 while decimal units use 1000 and that the displayed values remain correctly labeled.
