* ui: fix websocket connections on dev proxy `ember-cli` includes a handler for websocket upgrade requests to start proxying requests. Handling the same upgrade event by also proxying in `api.js` causes some kind of conflict where the connection is closed unexpectedly. The only change necessary on upgrade is to overwrite the Origin header so Nomad accepts the connection. * ui: remove unused variables
