Add a Recipe search card to /settings/ai: a SearXNG | Brave segmented control, the SearXNG URL pre-filled from the saved settings, or the Brave API key shown masked (last four characters) with Replace. The provider, URL and new key are a draft saved together with PATCH /api/v1/settings/recipe-search; Test calls the recipe-search test endpoint and shows "Found N recipes for 'chicken tikka masala'" or the error. The leave-without-saving guard moves to page level so it covers both the AI assistant form and the card; the shell test now renders in a data router as main.tsx does.
