fix(viewer): RegisterViewer defaults to post-tutorial TutorialState=100

BuildDefaultViewer hardcoded TutorialState=1 — correct for fresh anonymous
signups (RegisterAnonymousViewer) but wrong for AdminController.ImportViewer
and Steam-social signups, which both go through RegisterViewer and expect a
prod-replica viewer that boots to the home screen. Add an initialTutorialState
parameter (default 1 preserves RegisterAnonymousViewer behavior); RegisterViewer
passes 100.
