To keep the H1 titles of new templates consistent with the sticky menu options:
* change `Add email template` to `New email template`
* change `Add text message template` to `New text message template`
* change default letter template name `Untitled` to `New letter template`
Links need to work in isolation from their context
in the page.
This is an attempt at doing that. The one for
'Cancel' is still not ideal but 'Clear selection'
gives more information than 'Clear' about what it
does.
Also adds a 'href' attribute to the link, without
which its accessible role isn't recognised.
Adding a visually hidden live-region creates
duplication in the HTML. End result for users of
screen readers are that you get the same text read
out twice.
This adds `aria-hidden` to hide the visible
version and re-positions the live-region one next
to it. That means the live-region text appears in
the same place in the document order as the
visible one so things are announced as expected.
Inserts a hidden live region to ensure changes to
the count are announced.
The live region is hidden because it needs to be
in the initial markup of the page. The visual
counter is part of a larger region which is
inserted/removed from the DOM.

This was missed out of the work on improving focus
on the templates page.
When you clear the current selection, the 'clear'
link disappears so focus needs to be sent
somewhere.

Updated default letter template name from `Untitled` to `New letter template`
Most of the existing platform admin buttons on the service settings
page used to issue GET requests to switch service settings. This
means they weren't protected by CSRF. On top of that as our number
of service permissions increases over time a lot of buttons on the
page made it hard to work with.
To fix these issues we replace most of the buttons with rows in the
platform admin settings table. Each setting has a 'Change' link that
leads to a page with an On/Off switch form.
This removes "research mode" switch completely since we're planning
to deprecate it in the future and we don't expect to switch any new
services into research mode at the moment.
Most service permissions are now handled by a shared endpoint that
is parameterized with the permission name. Some permissions that
require some additional logic before they can be toggled (like document
upload, which requires setting a contact address) have separate
initial endpoints that redirect to `set_service_permission`.
"Archive", "Suspend" and "Resume" actions are kept as buttons since
they display a confirmation banner (which is a CSRF-protected form)
and they're not easily represented as an On/Off switch.
This adds a new OnOffField class that implements a boolean field
that is rendered as two On / Off radio buttons. This allows us to
avoid comparing 'on' and 'off' string values in the views since
the field takes care of transforming form data into python booleans.
This also adds a form class that can be used for any single On / Off
switch forms (e.g. service permissions).
This adds a preview pane which is visible when updating a letter brand.
If JavaScript is enabled, the preview pane shows on the set-letter-branding
page, and submitting the form saves updates the letter brand for a service
immediately. If Javascript is not enabled, there is a separate 'Preview email
branding' page which shows a preview of the brand and has a 'Save' button on it.
