Mike Dalessio e70047ca0f Default development environment to app.fizzy.localhost (#2822)
Using fizzy.localhost causes CORS errors when using minio for Active
Storage because the minio endpoint is at minio.fizzy.localhost — a
sibling subdomain, not a subdomain of the app host. Switching to
app.fizzy.localhost makes both hosts subdomains of fizzy.localhost,
resolving the CORS issue. See #2814 for the related minio CORS fix.

fizzy.localhost will continue to work if people want to use it, but all
docs and scripts have been updated to point to app.fizzy.localhost.
