Add update functionality for recipe metadata in RecipeRoutes and RecipeModal

- Introduced a new API endpoint to update recipe metadata, allowing users to modify recipe titles and tags.
- Enhanced RecipeModal to support inline editing of recipe titles and tags, improving user interaction.
- Updated RecipeCard to reflect changes in recipe metadata, ensuring consistency across the application.
- Improved error handling for metadata updates to provide clearer feedback to users.
