Add Hover Over to Explain what Batch Contact Status Means

Can we please ensure there are definitions for each Batch Contact Status when you hover over the Status? Some have definitions but others do not, or have unclear definitions.

"Sent" of course means that it was sent.

"Success" means that the interaction has produced an appointment.

This is not intuitive and you would not be able to guess success means an appt was booked from the transaction.
