fix(sw): 2026-10-21 SW design review and responsive header without More from 760px

User-approved design review (2026-10-21):
- SW Header: from 760px up nothing moves into More; the five menus stay with their
  titles (titles and values ellipsize), file name shrinks to 96px. Open next to the
  logo no longer blocks field shrinking above 760px (760/768 overflow fixed, also for
  configured `controls` headers). Dropdown yellow ring inside the button, black seam.
- Property Bar values as read-only red text; property popup "=" labels, read-only
  black values, per-entry hover with pointer.
- Home Menu recent files (3 rows, path + name caption, empty preview), Footer + slot
  guide off by default, Viewer file list without icons, Storybook widths 1920-760.
- Tests: old More expectations (integrated-improvement, keyboard-dismiss,
  footer-popup-viewer-refinement, storybook-cleanup-stage1) moved to the new rule;
  functional checks kept.
