wp_get_current_user() always returns a WP_User object (with ID=0 for guests), so the check `! $user` never triggered. This allowed user_id=0 to reach the Attendee constructor, which throws "invalid user id". Use get_current_user_id() and check for a falsy value instead.

PHP 8.4 deprecates implicit nullable types (e.g. Type $param = null). Updated all instances to use explicit nullable syntax (?Type $param = null) in event.php and event-date.php. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
