[APP] Regression in frontend when initializing Backbone

Looks like this is related to yarn build:app, which expects FIREBASE_URL to be available as an environment variable when called. In the short term, we can instead run FIREBASE_URL=<my-firebase-url> yarn build:app, but we may want to further improve the ergonomics around envify.

Edit: This is specifically caused by the removal of the default Firebase URL in config/development.json, which was previously set to https://duelyst-development.firebaseio.com/.

Resolving the above reveals another error:

server_status_manager.js:32 Uncaught TypeError: DuelystFirebase.Model is not a constructor

Looking into Backbone.js to investigate:

• Model.extend() should be returning a class (with a constructor): https://github.com/jashkenas/backbone/blob/1.2.1/backbone.js#L1818L1855
