Context

The local dev env is failing to connect to the webpack-dev-server because

1. it tries https://localhost:3035, but the server uses http://
2. the CSP is blocking the connections

Changes proposed in this pull request

Start the server with ssl and update the CSP to allow the connections.

Guidance to review

Visit https://localhost:3035/sockjs-node/ and accept/allow the self-signed certificate. Then open visit the app and check there are no related errors in the browser's dev console.
