refactor(storybook): fold SW Header Options stories into SW/Header

Remove the separate SW/Header/Options sidebar item. Its examples move to two
Stories directly under SW/Header (src/sw/sw-header-open.stories.tsx):
- Document Open: Open placement, label, 10-width responsive, composed bar,
  composed (controls) responsive
- Hidden Sub Controls: document New / Open and layer freeze / lock removal

No public API or component change. Tests and inventory follow the new IDs
(integrated 97/97, existing Stories pixel-identical 28/28, unused-removal
83/83). The two remaining overview failures are pre-existing historical
assertions (also failing on 5faa1f1), not new defects.
