Fix unified catalog: add map, tokens inside input, redirect from main

- Main page (/) now redirects to /catalog
- Catalog page uses CatalogPage component with map on the right
- Search bar tokens are now inside the input field (like Gmail)
- Removed separate grid components, using cards directly
- Added missing translations (refine, noResults)
