feat: enable live search on all recipe pages

Previously, live client-side search only worked on the main /rezepte and /recipes pages. All other pages (category, tag, favorites, search results, icon, and season pages) fell back to server-side search with form submission.

Now all recipe pages support live filtering as users type, providing consistent UX across the site.
