feat: enhance remote model search to use dynamic catalog

Replace hardcoded list of popular models with dynamic catalog from getCatalogModels().
Enable searching by model name or description and include model descriptions in results. Improves discoverability and maintains up-to-date model list without manual updates. Database files updated accordingly.
