<#
.SYNOPSIS
    Read-only dump of what the Veeam Backup for Microsoft 365 cmdlets return, for troubleshooting
    the collector.

.DESCRIPTION
    The collector reads properties of Get-VBOJob / Get-VBOJobSession results whose names aren't
    fully documented. This prints those objects' real structure (property names, types, values and
    each date's Kind, a few levels deep) for a few jobs and their latest sessions. Nothing is
    changed. Output is also saved to a text file.
