refactor(home): URL-Import verzog ins Register

Import-von-URL-Form war unter dem Hero-Suchfeld auf der Home-Seite —
dort etwas deplaziert, weil die Home-Seite primär Suche + Listen
zeigt. Jetzt sitzt das Feld oben auf der /recipes-Seite (Register),
dem natürlicheren Ort zum Verwalten der Sammlung. Link-Icon links,
grüner „Importieren"-Button rechts, auf allen Viewport-Größen sichtbar.
