Add copy explaining how the follow up days are calculated

[mitchelljkotler]

It is 30 days for federal and 15 days otherwise, unless they provide an estimated completion date, in which case we use that. In either case, there should be an explanation so users understand how often we follow up.

Question: can a user revise the response time?

Defaults:

• Fed: This request is with a federal agency, so we will follow up in 30 days.
• Not Fed: This request is with a {jurisdiction} agency, so we will follow up in 15 days.

Custom:

• On {Date} the agency let us know that the request will take {Direct Quote, eg. 180 days} to complete. So we'll follow up in {our format, eg. "5 months and 4 weeks."}
• On {date} this agency let us know that the request will take {time to estimated completion date} to complete so we will follow up then.

This is going to be a hard fix because the code is old and has a lot of legacy baggage.

This is something we probably need to table. But we could tag it "fundable redesign work".
