Feature Request: Edit Book UI with Optimistic Update

Allow users to edit existing book details using a modal or dedicated edit page. The UI should optimistically update book details while waiting for the server response.

🎯 Proposed Solution

• Add Edit button on each book card.
• Create EditBook.tsx or modal-based editor.
• Pre-fill form with existing data.
• PUT /api/books/:id for saving updates.
• Implement optimistic updates and rollback if the request fails.

✅ Expected Behavior

• User can edit book fields and save.
• UI updates immediately on save click.
• Changes persist after backend confirmation.

💻 Technical Notes

• Maintain a local copy of book data for rollback if needed.
• Use React Query or manual state updates for optimistic UI.

🧪 Test Steps

1. Open edit form for a book.
2. Modify title or author → save changes.
3. Observe instant update and confirmation after server response.
