fix: Landing cleanup: 404 route, German comments, dead code, orphaned heading (#306)

- Add /:pathMatch(.*)*  catch-all route that redirects to / so unknown
  URLs no longer render blank
- Replace German inline comments in scrollBehavior with English equivalents
- Remove seven dead `// group: "navbar"` comments from /docs route and its
  child routes (the live group: 'navbar' property on the parent is kept)
- HomeView.vue and HomeViewMixed.vue already carry the renamed
  "Verified On-Chain" heading with supporting copy; no changes needed there
