Update template description

survey_sent Indicates that a survey was sent. Valid values are positive integers and zero. In case it was decided not to send a survey, the selected value is 0.

• It is not clear that the integer describes the number of sent-out surveys.

• Further, it should be either equal/smaller than the number of clients.

• Question: Should you fill out the number before you send surveys out (it will probably not change at the point you fill out the survey.)
