- Use safe .get() in RecipeCache._resort_locked instead of itemgetter to prevent KeyError when recipe missing created_date; align sort key with _sort_cache_sync (prefer modified, fallback created_date, fallback 0)
- Add base_model to allowed_fields in persistence_service.update_recipe() so the field passes validation
- Route bulk base model updates through updateRecipeMetadata() on recipes page instead of generic saveModelMetadata(), matching existing isRecipesPage pattern used in setBulkFavorites and saveBulkTags
