feat(cms): "View site" link in admin header (MITHOME-97 follow-up)

User request: there was no way to get from the Payload admin back to
the public website — confirmed live (read_page on the admin nav showed
only internal links: collections, globals, account, logout).

Added a "🌐 Honlap megnyitása" link next to the QuickSearch box
(src/components/admin/QuickSearch.tsx — same header slot, no new
admin.components entry or importmap regen needed since the export name
didn't change). Opens in a new tab, points at siteConfig.general.url
(NEXT_PUBLIC_SITE_URL), so it resolves to the correct site per
environment automatically — stage.mozdit.hu on staging, the production
domain once that's live.

Verified live in the browser: link renders next to the search box,
resolves to the expected URL (find() confirmed the href), zero new
console errors in a fresh tab. Gate: tsc, lint, unit tests (51 passed),
production build all green.
