Invoke AzAutomationJobCleanup

<#
.SYNOPSIS
    Maintenance script to clean up old Automation Job history.

.DESCRIPTION
    Azure Automation keeps job logs which can be noisy.
    This script finds jobs older than X days and effectively clears them from view 
    (though archiving is native, this is for operational dashboard cleanup).
    
    Note: Can't delete jobs via simple cmdlet easily, often used to just export-and-purge logic.
    Here we focus on identifying the purge candidates.
