Support dark mode

[w4nn4]

Current Behavior

Everything is white, I've updated the following to convert to dark mode. If this can be implemented as a switch or set in the config files.

Possible Solution

Modify euc-monitoring.css

.body {
	background-color: #000000;
}

.bg-background {
	background-color: #000000;
}

Modify Get-DonutHTML.ps1 line 60, fill black.

    $HTML += "<circle class='donut-hole' cx='21' cy='21' r='15.91549430918954' fill='#000'></circle>"

Add to New-HtmlReport.ps1 under line 83.
"<div class='bg-background'>" | Out-File $HTMLOutputFileFull -Append

Context

We run dark mode dashboards so EUC monitoring was a eyesore.
