Add development tooling to use live NeoPass, kinda

Hacky and inconvenient, but it works!

I want this primarily to enable me to live-debug what info we're
getting back in the auth token. In production right now, the flow with
NeoPass succeeds, but we fail to create the account, and my production
error logs say it's because the username field is too long. I had hoped
it would just be the Neopets username, but now that I've poked at
NeoPass itself a bit, I'm realizing it won't be that simple.

So, we'll use this to investigate!

# Note that this does *not* allow you to just use NeoPass with the
# development server as one might like! Our `localhost:3000` redirect URL is
# not registered with live NeoPass, so we have to provide the production
# callback, or else NeoPass will reject the initial auth request altogether!
#
# Instead, you'll need to somehow intercept the flow:
# 1. Dress to Impress (development) sends you to NeoPass, with production
# configuration in the request.
# 2. NeoPass redirects back to Dress to Impress (production).
# 3. Use some kind of tool to prevent the above redirect, and rewrite it
# to `localhost:3000` instead.
# - For me, it's convenient to do this via the Burp Suite's "Proxy"
# tool: intercept the request, cancel it, and manually rewrite the
# URL and navigate to it.
# - Another way I've used for similar things in the past is to edit my
# /etc/hosts file to temporarily point `impress.openneo.net` to
# `127.0.0.1`. Then, when the request fails, manually rewrite the
# URL and navigate to it.
# - I suppose you could also have your browser's Network panel persist
# logs, then you can see the `/users/auth/neopass/callback` request
# that fails and redirects back to the production sign-in page, and
# manually rewrite it? (The request should be safe to let through,
# because production DTI will reject the callback, because it knows
# from the `state` parameter that it didn't initiate this flow.)
