Issue Title: Update Login Notification to Use Toast Instead of Alert

Description:
Currently, our application displays an alert when a user logs in. To improve user experience and modernize our notification system, we should update this behavior to show a toast notification instead of an alert.

Steps to Reproduce:

1. Open the application.
2. Navigate to the login page.
3. Log in with valid credentials.

Expected Behavior:
Upon successful login, a toast notification should appear confirming the login instead of using an alert.

Additional Information:

• Our current alert-based notification system is outdated and lacks the visual appeal of modern applications.
• Using a toast notification will provide a more user-friendly and intuitive way to notify users about successful login actions.
• This change aligns with industry standards and enhances the overall user experience of our application.
