Show Billing Account Instead of Company in RailsAdmin when applicable
Problem
If a Customer account has any BillingAccountMemberships, we show the Billing Account (Zuora) Name as the Company name field in the user-facing portal customers.gitlab.com/billing_accounts, but on the admin side it always shows Company.
Additionally, it does not appear to be possible to modify Customer.company at all when the Customer has a BillingAccount. The customer-facing interface only allows modifying the Billing Account Name, and the RailsAdmin interface does not allow modifications to Customer.company.
Proposal
Show Billing Account name in cDot admin > Customer record when one is present
Optionally: if Customer.company has any use at all while a BillingAccountMembership exists, make Company a modifiable field.
