Show consistent information for renewal dates and prices for plans, domains, and email

### What

If you want to view a purchase's renewal date and price, the only places to do so are at _Upgrades > Purchases_ or from the account Purchases page (`/me/purchases`).

However, some of this information is inconsistently shown in other areas:

* At _Upgrades > Plans_ under the **Plan** tab, your current plan is shown with its price but without the renewal date.
* At _Upgrades > Plans_ under the **My Plan** tab, the renewal date is shown, but not the price.
* At _Upgrades > Domains_, and after clicking a domain and viewing the **Details** section, the renewal date is shown, but not the price.
* At _Upgrades > Emails (> domain)_, the renewal date is shown, but not the price.

I propose that the renewal (or expiration) date _and_ cost for a plan, domain, or email subscription should be shown in these areas.

### Why

Many users expect to see basic billing details for a subscription when viewing its details in the _Upgrades_ area, instead of having to make extra clicks to either of the Purchases pages. This would also make for a more consistent UI for the three main types of upgrades.

Initial request: in 6707632-zd-a8c, user expected to see their domain's renewal price listed on their domain's info page.
