This changeset removes webauthn from the Notify.gov admin app. We are not using webauthn at all in our implementation and will be looking at an entirely different authentication system in the near future.

On the ‘find user’ page it says ‘sms_auth’ instead of ‘Text message
code’.
This commit fixes that, and adds a handy formatter so it’s easier to do
the right thing in the future.
Having this as a function which does string parsing and manipulation
surprised me a bit when I was trying to figure out why something wasn’t
working.
It’s more in line with the way we do other config like this (for example
`ASSET_PATH`) to make it a simple config variable, rather than trying to
be clever and guess things based on other config variables.
It’s also less code, and is explicit enough that it doesn’t need tests.

At the moment, we are not doing any transformation of features before
applying geometric algorithms to them. This is, in effect, assuming that
the earth is flat.
This new version of utils implements the transformation of our polygons
to a Cartesian plane. In other words, it converts them from being
defined in spherical degrees to metres.
For the admin app this means we need to convert places where the code
expects things to be measured in degrees to work in metres instead.
We give estimates of the area for those who can’t see the map. These
estimates were needlessly precise, gave a false sense of accuracy and
were causing intermittent test failures between different environments.
This commit rounds them in the same way that we round the count of
phones.
This adds Yubico's FIDO2 library and two APIs for working with the
"navigator.credentials.create()" function in JavaScript. The GET
API uses the library to generate options for the "create()" function,
and the POST API decodes and verifies the resulting credential. While
the options and response are dict-like, CBOR is necessary to encode
some of the byte-level values, which can't be represented in JSON.
Much of the code here is based on the Yubico library example [1][2].
Implementation notes:
- There are definitely better ways to alert the user about failure, but
window.alert() will do for the time being. Using location.reload() is
also a bit jarring if the page scrolls, but not a major issue.
- Ideally we would use window.fetch() to do AJAX calls, but we don't
have a polyfill for this, and we use $.ajax() elsewhere [3]. We need
to do a few weird tricks [6] to stop jQuery trashing the data.
- The FIDO2 server doesn't serve web requests; it's just a "server" in
the sense of WebAuthn terminology. It lives in its own module, since it
needs to be initialised with the app / config.
- $.ajax returns a promise-like object. Although we've used ".fail()"
elsewhere [3], I couldn't find a stub object that supports it, so I've
gone for ".catch()", and used a Promise stub object in tests.
- WebAuthn only works over HTTPS, but there's an exception for "localhost"
[4]. However, the library is a bit too strict [5], so we have to disable
origin verification to avoid needing HTTPS for dev work.

This matches the existing performance platform page, and I think is a
bit easier to read for high-level numbers where you don’t need to see
that they’re changing second-by-second.
