Make it clear which template you’re sending

The one downside of skipping the template page is that you no longer
get such strong confirmation that you’ve picked the correct template.
You still see the preview of the template, but it’s further down the
page, and the name of the template has disappeared.

This commit adds the name of the template to the page title, to:
- have some continuity from the previous page
- make it easier to double-check you’ve chosen the correct template
