Reduce bundle size

[austinhallock]

This is obviously very low priority, but here's what the current breakdown of bundle size is

Some big boy libraries in there:

• vue-phone-number-input (upgrading to v1+ will fix part of that (info). But probably should dynamically import this.
• moment (https://github.com/UPchieve/web/issues/409)
• sentry (try importing just what you need instead of *)
• lodash (import just what you need instead of _ from "lodash), and you might need to use lodash-es
• awesome-phonenumber dynamic import
• socket.io/engine.io/vue-socket.io not sure for this one. Socket.io has a slim version, but you'd have to fork vue-socket.io to use it, so probably not worth it

To get the bundle size breakdown (image above), you can use BUNDLE_ANALYZER=1 npm run build if #410 gets merged
