Consolidate page templates for emails + texts

Use one page template for each of:
- choosing a message template
- adding recipients
- checking an email message
- looking at a job

This commit consolidates the two templates into one, and adds logic to show
the SMS message pattern or the email message pattern depending on the type of
template.

It also gives email templates a bit more width, because the body and the from
address tend to be quite long.
