Lazy-load paths

[mcab]

We didn't really need to have the entire app load at the start. We would ideally want to lazy-load paths, but due to the way either:

1. service-worker.js served files
2. Webpack bundled those files

we weren't seeing them appear in the PWA.

My guess is that it's closer to 1; while serving in dev mode, Webpack was easily able to bundle and serve the files normally.
