Fix missing property promotion in soft delete constraints

The $data and $deletedAtColumn constructor parameters were not promoted
to properties, causing "Undefined property" errors when accessing
$this->data and $this->deletedAtColumn in matches() and toString().

Added 'protected' keyword to enable constructor property promotion.
