refactor: Update email query in update_email view to handle new_email…

… validation

This commit updates the email query in the update_email view of views.py. It adds a validation check for the new_email field to ensure that it is a valid email address before updating the company's email. This change improves the data integrity and prevents invalid email addresses from being saved.
