Add new dimension to MBD and potentially DiamondHands endpoints to help partners identify if low score is due to poor quality transactions or lack of transactions

[lebraat]

User Story:

As a partner
I want to better understand if a low score coming from MBD or DiamondHands is due to low transaction volume or poor transactions
So that I can adjust how I treat the user.

Acceptance Criteria

GIVEN a request to the MBD or DiamondHands API (tbd)
WHEN a user scores low
THEN a secondary field can help me understand if this is due to low transaction volume or poor transactions

Add a new '-1' response that indicates no or insufficient data to score
