People picker ListBox used MouseBinding which fires before SelectedItem
updates, causing null CommandParameter. Replaced with SelectionChanged
event handler in code-behind.
AuditUsersAsync created TenantProfile with empty ClientId, causing
ArgumentException in SessionManager. Added currentProfile parameter
to pass the authenticated tenant's ClientId through.

for admin URL, eliminating second browser auth prompt
Resolves: UAT issue "Must specify valid information for parsing in the string"
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
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.

- BulkSiteService creates Team sites via TeamSiteCollectionCreationInformation with owners/members
- BulkSiteService creates Communication sites via CommunicationSiteCollectionCreationInformation with generated URL
- Per-site error handling via BulkOperationRunner with continue-on-error semantics
- SanitizeAlias generates URL-safe aliases from site names for Communication sites
- BulkSiteServiceTests: 3 pass (interface check + model defaults + CSV parsing), 3 skip (live SP)
- Fixed pre-existing BulkMemberService.cs Group type ambiguity (MSCSC.Group vs Graph.Models.Group)
- Replace stub with full grouped HTML export (port of PS Export-DuplicatesToHTML)
- One collapsible card per DuplicateGroup with item count badge and path table
- Uses System.IO.File explicitly per WPF project pattern
- 3/3 DuplicatesHtmlExportServiceTests pass; 9/9 total export tests pass
- 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
- File mode: Search API KQL pagination matching SearchService pattern
- Folder mode: CAML FSObjType=1 via SharePointPaginationHelper.GetAllItemsAsync
- MakeKey composite key (name+size+dates+counts) matches DuplicatesServiceTests scaffold
- Groups only items with count >= 2, ordered by group size then name
- ExtractLibraryFromPath derives library name from path relative to site URL
- SelectProperties added per-item (StringCollection has no AddRange)
- KQL builder for extension, date, creator, editor, library filters
- Pagination via StartRow += 500, stops at MaxStartRow or MaxResults
- Filters _vti_history/ version history paths from results
- Client-side Regex filter on file name and title

- With FolderDepth>0, CollectSubfoldersAsync recurses into child folders
- All CSOM calls use ExecuteQueryRetryHelper.ExecuteQueryRetryAsync (3 call sites)
- System/hidden lists skipped (Hidden=true or BaseType != DocumentLibrary)
- Forms/ and _-prefixed system folders skipped during subfolder recursion
- ct.ThrowIfCancellationRequested() called at top of every recursive step

- Inline JS filterTable() function for client-side row filtering
- WriteAsync uses UTF-8 without BOM for HTML
- All 3 HtmlExportServiceTests pass
[Rule 3 - Blocking] CsvExportService/HtmlExportService stubs added so export test
files compile. [Rule 1 - Bug] PermissionsService: removed Principal.Email (not on
Principal, only on User) and changed folder param from Folder to ListItem (SecurableObject).
