Update labels to match what is in the COP

Problem/Motivation

Currently the labels for the fields for the Account Information do not match what is in the COP https://cop.usps.com/cop-navigator

It is not quite clear which field in the COP / Business Center corresponds to the form. Below is what I believe the mapping should be with suggested label changes.

User interface changes

Account Number --> Master Mailer ID (MID)
Customer Registration ID --> Customer Registration ID (CRID)
