Auto-apply startup items from profile, Configure-PC -MachineNumberOnly

Three changes to eliminate the redundant startup-item picker during
the imaging chain:

06-OrganizeDesktop.ps1 - new Phase 3: auto-apply startup items
  Reads pcProfile.startupItems (or site-wide default) and creates
  .lnk files in AllUsers Startup folder. Supports exe, existing, and
  url types (same as Configure-PC). Idempotent - skips items that
  already exist so manual changes aren't overwritten. Runs during
  shopfloor setup finalization, so the tech doesn't need to select
  startup items again.

Configure-PC.ps1 - new -MachineNumberOnly switch
  When set, skips the entire startup-items section and only shows the
  machine number prompt (if UDC/eDNC at 9999). Used by sync_intune
  -AsTask after completion. Full startup picker still available when
  the tech opens Configure-PC.bat manually from the desktop.

Monitor-IntuneProgress.ps1 - simplified -AsTask completion
  After post-reboot DSC complete: unregisters task, launches
  Configure-PC -MachineNumberOnly, exits. Tech uses sync_intune.bat
  on the desktop to see QR code for inventory purposes.
