test(sw): approve the SW Viewer Header API and Storybook cleanup baselines

Test-only approval commit after the 34f02bf main merge (sw-test-regression-
baseline section 9); no protected path changes.
- public-api.approved.json from the clean 34f02bf build: 170 exports kept,
  only SWViewerHeader.d.ts changes (7 optional SWViewerHeaderProps).
- approvedMainCommit b4e0771 -> b320a8f; approvedHeaderDeclarations for the
  23d522c Story declarations; withApprovedOrder for the approved SW Header
  first position; storybook-simplification expects SW/Theme hidden.
- Verification report: docs/sw/sw-viewer-storybook-merge-verification-2026-10-21.md
