Fix incomplete global policy scope detection in Test-Assessment.35015

[Copilot]

The global policy detection logic was only checking ExchangeLocation for 'All' scope, missing globally-scoped policies that target SharePoint, OneDrive, or ModernGroup locations.

Changes:

• Check all four location properties (ExchangeLocation, ModernGroupLocation, SharePointLocation, OneDriveLocation) for 'All' scope
• Detect policies with no location scoping (all locations empty), which apply globally by default
• Align with the pattern used in Test-Assessment.35004.ps1

Before:

$globalPolicies = $labelPolicies | Where-Object {
    ($_.ExchangeLocation -contains 'All') -or
    ((-not $_.ModernGroupLocation -or $_.ModernGroupLocation.Count -eq 0) -and
     (-not $_.ExchangeLocation -or $_.ExchangeLocation.Count -eq 0))
}

After:

$globalPolicies = $labelPolicies | Where-Object {
    ($_.ExchangeLocation    -contains 'All') -or
    ($_.ModernGroupLocation -contains 'All') -or
    ($_.SharePointLocation  -contains 'All') -or
    ($_.OneDriveLocation    -contains 'All') -or
    (
        (-not $_.ModernGroupLocation  -or $_.ModernGroupLocation.Count  -eq 0) -and
        (-not $_.ExchangeLocation     -or $_.ExchangeLocation.Count     -eq 0) -and
        (-not $_.SharePointLocation   -or $_.SharePointLocation.Count   -eq 0) -and
        (-not $_.OneDriveLocation     -or $_.OneDriveLocation.Count     -eq 0)
    )
}
