Phase 08 Plan 02: ViewModel Toggle Logic Summary

IsSimplifiedMode and IsDetailView toggles on PermissionsViewModel with computed SimplifiedResults, Summaries, and ActiveItemsSource -- all mode switches rebuild from cached Results without re-scanning SharePoint.

Tasks Completed

Task 1: Add simplified mode properties and summary computation to PermissionsViewModel

• Commit: e2c94bf
• Files: SharepointToolbox/ViewModels/Tabs/PermissionsViewModel.cs
• Added IsSimplifiedMode and IsDetailView observable properties with partial change handlers
• Added SimplifiedResults (IReadOnlyList) and Summaries (IReadOnlyList) as manually-raised properties
• Added ActiveItemsSource computed property returning correct collection for DataGrid binding
• RebuildSimplifiedData() wraps Results via SimplifiedPermissionEntry.WrapAll and builds summaries
• RunOperationAsync (both dispatcher and else branches) calls RebuildSimplifiedData when IsSimplifiedMode is active
• OnTenantSwitched resets SimplifiedResults and Summaries to empty arrays

Deviations from Plan

None - plan executed exactly as written.
