Feature Request: Implement Toast Notifications for User Feedback

**Description**

Currently, success and error messages for user actions (such as sign-up, sign-in, or server errors) are displayed directly on the page. A better approach is to use toast notifications, which provide a seamless and non-intrusive way to deliver feedback to users.

**Benefits of Toast Notifications:**

1. Improved User Experience
2. Enhanced Aesthetics
3. Better Visibility

**Proposed Solution**

Integrate a toast notification system to display real-time feedback for user actions.
