Merchant ID Validation in QueenBee

In QueenBee, a Merhcant ID can be configured to set up the integration with Tuition Express, however it is a free form number entry and can have user error introduced that causes problems downstream.

It would be helpful to enforce either a soft check that the number is 11 digits long, or even better, if it could make a call to the payments API to validate that the entered TIED is indeed valid and active.

This idea was following the recent 'incident' related to an increase in TE errors after a TEID was entered incorrectly.
