nav: add "Guides" (Application Guide) to top bar and Resources menu

Add a "Guides" link pointing at /application-guide/ in two places:
- the top utility bar, between Blog and Docs (both the Nuxt AppUtilityBar.vue
  and the 11ty top-utility-bar.njk mirror)
- the Resources mega-menu's Reference column, above Docs (desktop with a
  book-open icon + mobile), in src/_data/chrome.json

Bump the Reference column row-span and the Resources dropdown grid repeat()
so the layout guardrail test (chrome.test.mjs) stays green.
