Adds HTML title elements to templates that extend either `base.html`,
`portico.html` or `portico_signup.html`, and that are not website
portico landing pages that will use the `PAGE_TITLE` variable to set
the HTML title element (see following commit in series).
Also, updates some templates for missing translation tags.
As a general rule, we want the title element (and page content)
translated. Exceptions that are updated in this commit are templates
used in the development environment, analytics templates that are used
by staff and templates related to Zephyr.
I remove some spurious whitespace and a stray period
in zephyr-mirror, and then for all three I try to
line-wrap/indent in a way that's nicer for humans
and parsers to read.
The check-handlebars-templates script now looks at most of our
back end templates to try and find imbalanced tags. This commit
fixes a bunch of the existing templates.
