Add "Add to Shelf" functionality on Search Results page

[shehbazjafri]

For every book fetched by search results, there should be a button to quickly add a book to a shelf.
We're simplifying the way users add books to their shelves from search results. Currently, it's a bit clunky, but we're introducing a "Quick Add" or "Add to Shelf" button for each book in the search results. This nifty feature lets users effortlessly pop a book onto their shelf with just one click, no more navigating through extra screens or forms. We're making it quick and easy, so users can focus on enjoying their books without the hassle. This update involves frontend and backend work, some design considerations, and thorough testing to ensure a seamless user experience. Once implemented, users will appreciate the smoother and more convenient book-management process right from the search results page.
