test(sw): align legacy storybook suites and add header composition fixture

- dropdown-consolidation, storybook-cleanup-stage1, detail-buttons, property-panel-comparison: assert their recorded
  state and accept today only the approved later Story changes (storybook-inventory.mjs helpers).
- header-composition.browser.mjs + fixtures/header-composition.tsx: the removed Composition Story presets, hidden
  controls, invalid menuOrder / hiddenControls and live changes, on a test-only page using the public API only.
- storybook-unused-removal: header comment lists which older scripts run on current Stories again.
