Fix two pre-existing blockers found during UAT:
- ProfileManagementViewModel: add NotifyCanExecuteChanged on property changes
- SessionManager: open browser in openBrowserCallback (was no-op)
Remaining blocker: SitePickerDialog parsing error from PnP Framework.

- TransferViewModel: add _hasLocalSourceSiteOverride field
- Override OnGlobalSitesChanged to pre-fill SourceSiteUrl from first global site
- Add OnSourceSiteUrlChanged partial to detect local user input
- Reset _hasLocalSourceSiteOverride on tenant switch
- BulkMembersViewModel confirmed excluded: no SiteUrl field, CSV-driven, no OnGlobalSitesChanged override added
- StorageViewModel: add OnGlobalSitesChanged, OnSiteUrlChanged, _hasLocalSiteOverride
- SearchViewModel: add OnGlobalSitesChanged, OnSiteUrlChanged, _hasLocalSiteOverride
- DuplicatesViewModel: add OnGlobalSitesChanged, OnSiteUrlChanged, _hasLocalSiteOverride
- FolderStructureViewModel: add OnGlobalSitesChanged, OnSiteUrlChanged, _hasLocalSiteOverride
- All four VMs pre-fill SiteUrl from first global site; local typing sets override flag
- Tenant switch resets _hasLocalSiteOverride in all four VMs
- Replace hardcoded EN strings with TranslationSource.Instance lookups
- Uses toolbar.globalSites.count (formatted) and toolbar.globalSites.none keys
- Follows same pattern as PermissionsViewModel.SitesSelectedLabel
- Add _hasLocalSiteOverride field to track local user selection
- Override OnGlobalSitesChanged to pre-populate SelectedSites from global sites
- Set _hasLocalSiteOverride=true when user picks sites via site picker dialog
- Reset _hasLocalSiteOverride=false on tenant switch (OnTenantSwitched)
- 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
