Add visibility to Spoke administrators on pricing plan applied

Is your feature request related to a problem? Please describe.
Spoke administrator needs to know which pricing model will be applied to the texts sent or a cost estimator so they can accurately assess costs.

Describe the solution you'd like
I can leave the engineer to determine the best solution in the timeframe, but I thought that simply stamping 10DLC registered or unregistered somewhere visible would be good enough (a pop-up or call-out?). A better solution would be a cost estimator. Would like this before July 1st so clients will know which pricing model they are sending on. Before July 1st would be even better as it could push clients to reach out to us to make sure we move them on to 10DLC.

Describe alternatives you've considered
Be very very good at notifying clients when they are actually on 10DLC and when they are not.
