- DuplicatesViewModel: ModeFiles/Folders, criteria checkboxes, group flattening to DuplicateRow
- Uses TenantProfile site URL override pattern (ctx.Url is read-only)
- ExportHtmlCommand exports DuplicateGroup list via DuplicatesHtmlExportService
- DuplicatesView.xaml: type selector, criteria panel + flattened DataGrid
- DuplicatesView.xaml.cs: DI constructor with DataContext wiring
- SearchViewModel: full filter props, RunOperationAsync via ISearchService
- Uses TenantProfile site URL override pattern (ctx.Url is read-only)
- ExportCsvCommand + ExportHtmlCommand with CanExport guard
- SearchView.xaml: filter panel + DataGrid with all 8 columns
- SearchView.xaml.cs: DI constructor with DataContext wiring
- Rule 1: Fixed ctx.Url read-only bug — use new TenantProfile with site URL for GetOrCreateContextAsync
- Rule 3: Added missing System.IO using to SearchCsvExportService and SearchHtmlExportService
- Create Views/Dialogs/ProfileManagementDialog.xaml (modal Window with Name/TenantUrl/ClientId fields and TranslationSource bindings)
- Create Views/Dialogs/ProfileManagementDialog.xaml.cs (DI constructor injection, LoadAsync on Loaded)
- Add OpenProfileManagementDialog factory delegate to MainWindowViewModel
- Wire ManageProfilesCommand to open dialog via factory, reload profiles after close
- Register ProfileManagementDialog as Transient in DI (App.xaml.cs)
- Inject IServiceProvider into MainWindow constructor for DI-resolved dialog factory
