Repair ServerStatus admin info command

[DavidRieman]

The ServerStatus.cs file/command are getting disabled for a move from netcoreapp3.1 to net7.0 to improve forward-mobility on our dependencies, as the command relies on Windows-only API. (.NET 7 targeting any OS will help us largely retain cross-platform compatibility even though Windows is our primary development and support platform.)

For this ticket, we should investigate if there is an OS-agnostic safe way to query some server health statistics similar to what we had with the ManagementObjectSearcher queries, else see if .NET 7+ gives us any way to still run the code but safely/conditionally on Windows only and implement that instead.
