Queue Monitor fails when queue-monitor.ui.show_metrics == FALSE

[jschlies]

Looking at ShowQueueMonitorController, I see that when queue-monitor.ui.show_metrics == FALSE, $metrics is NULL and passed to view queue-monitor::jobs.

Looking in view queue-monitor::jobs, I see that $metrics->all() is called with no NULL check causing failure.

I suggest that view queue-monitor::jobs. should be updated to:
`

@if(config('queue-monitor.ui.show_metrics'))

@foreach($metrics->all() as $metric)
@include('queue-monitor::partials.metrics-card', [
'metric' => $metric,
])
@Endforeach

@endif

`
PHP 8.2

If I'm misinformed, please correct me, If asked, I will happily make a PR.

Otherwise, very happy with package

Thanks,
Jim
