Stop WPForms Emails on Staging Sites

Turns off all WPForms notification emails when the site is not running as production, so test submissions on staging never reach clients.

Code

add_filter( 'wpforms_disable_all_emails', function ( $disabled ) {
    return 'production' !== wp_get_environment_type() ? true : $disabled;
} );

Relies on WP_ENVIRONMENT_TYPE being set to staging, development or local on non-live copies.
