There is a number of issues most of them are not because of changes in this PR, but let's still fix them.

1. I get toSignal error. Can be fixed by adding .pipe(startWith(0)) to refreshInterval$ in WidgetResourcesService.
2. I've tried simulating load on CPU to test the widget and noticed that load is reported as System on main chart, but bars don't show much. Looks like an issue with MW reporting. I think users would expect to see total load on bars as well.

3. Memory overview widget doesn't load. 4. Let's remove CPU Usage Per Core from default set of widgets as currently there is a gap there.

Besides the discrepancy between CPU load in various widgets (System vs User), the rest looks good.
Let's ask MW to look into this.

I don't know why this package is needed. It's not used anywhere and it works for me without it. Sounds like an issue on your end.
