    .SYNOPSIS

        Returns whether a Windows Event Log source is already registered.

    .DESCRIPTION

        Thin wrapper around [System.Diagnostics.EventLog]::SourceExists(), extracted into its

        own function so Write-EventLogEntry's source-creation branch can be unit tested with a

        mock instead of depending on real Windows Event Log state or elevation.

    .PARAMETER Source

        The event source name to check.

    .OUTPUTS

        Boolean.

    .EXAMPLE

        Test-EventSourceExists -Source 'Posh-Certutil'

        [Parameter(Mandatory)]
