Swagger UI loads slowly for devs

[slifty]

We broke our specification into lots of files (yay!) with #1178.

When deploying, those files are bundled as part of deploy; when serving locally, however, those files are served dynamically which results in hundreds of individual API calls. This means npm start => loading localhost:3001 will require waiting some amount of time for the browser to load all the specification pieces.

This isn't ideal; I don't want to prescribe a solution in the issue definition, but if there is no clear way to speed this up we might want to somehow modify our start command to have the service render a built copy of the spec / rebuild on file change.

I usually run these commands locally so that I get something like production:

npm ci && npm run lint && npm run build
export NODE_EXTRA_CA_CERTS=/path/to/selfsigned/fullchain.pem && npm run migrate && node dist/index.js
