Implement integration of register APIs in the frontend application. Refer to the backend APIs provided by [HacktoberBlog/SpringBootBackend](https://github.com/HacktoberBlog/SpringBootBackend) for endpoints and registration logic. - Connect frontend registration forms to backend registration endpoints. - Handle API requests and responses for user registration. - Display errors and success messages appropriately using react-toast. - Implement form validation for registration fields. - Ensure secure transmission of credentials during registration. This issue will enable new user registration by leveraging backend APIs.
