- Add string? UserType as last positional parameter to GraphDirectoryUser record
- Add bool includeGuests = false parameter to IGraphUserDirectoryService.GetUsersAsync
- Branch Graph filter: members-only (default) vs all users when includeGuests=true
- Add userType to Graph Select array for MapUser population
- Update MapUser to include UserType from Graph User object
- Add MapUser_PopulatesUserType and MapUser_NullUserType tests

- GraphUserDirectoryService uses PageIterator<User, UserCollectionResponse> for pagination
- Filter: accountEnabled eq true and userType eq 'Member' (no ConsistencyLevel header)
- Cancellation checked in PageIterator callback (return false stops iteration)
- Progress reported via IProgress<int> with running count per user
- MapUser extracted as internal static for direct unit test coverage
- Tests: 5 unit tests for MapUser field mapping and fallback logic
- Integration-level tests (pagination/cancellation) skipped with rationale documented
- Note: test project compilation blocked by pre-existing BrandingServiceTests.cs (10-01 artifact)
