Align subscription expiration notification emails with being unable to renew 15 days prior to expiration
Problem
In #3268 (closed), we disabled the renew button in CustomerDot until 15 before expiration. We do, however, send renewal reminders out from Zuora 90 days in advance, and again at 45 and 30, with instructions to login to CustomerDot to manage the subscription. Some customers may find this confusing to login and then not actually be able to renew for several more weeks or longer, since we didn't widely communicate the 15-day restriction.
Proposal
Update the outgoing expiration emails with additional info on the 15-day restriction.
