- Updated the RecipeRoutes and RecipeScanner to accommodate the new search options, enhancing the filtering capabilities.
- Refactored RecipeManager and RecipeSearchManager to utilize the hierarchical state structure for managing search parameters and pagination state.
- Improved the user interface by dynamically displaying relevant search options based on the current page context.
