Add a label in Follow-Up sections in the Portfolio after due dates

In order to be more effective, we have to make MYLE easy to understand.

Add a little number (3), exactly like in the failed fax section on Follow-up sections when items reach the due date would be a great improvement.

No need for the practitionner to go every week check manually if there are items with due dates, it will shows up automatically.

It makes the use of MYLE totally equal in every sections.
