feat(alert): include license names, SKUs and account status in inactive licensed users alert

The alert already fetched assignedLicenses and accountEnabled from Graph
but dropped them from the emitted alert data. Surface license display
names, raw SKU IDs, account enablement and days since last sign-in so
the alert can be actioned without a follow-up lookup.
