Added a try-except block in views.py to prevent the model from creating a subscription when an email already exists in the database.

Included an `if-else` block in `SubscribeFormHandler.js` to display a success message only if the user is successfully subscribed.

Previous Code:

NewsletterSubscription.objects.filter(user=user, email=email.lower()).exists()

Updated Code:

try:
    NewsletterSubscription.objects.create(user=user, email=email)
except IntegrityError:  # Except block to catch the error
    error_msg = \"A user with that email already exists.\"

return is_valid, error_msg

Workflow Users can subscribe only if they have not previously registered with that email address. If they have already subscribed, they will receive an alert indicating that they cannot use that email again. If the subscription is successful, they will be shown a tailored message confirming their subscription.
