refactor(homeView): organize directory structure

Part 1 of 2, not controversial I hope — just takes our big blob of files and organizes them into folders.

(Part 2 will be a little more drastic, so I'll split that out into a separate PR for discussion)

Before: most things sitting at the root

After: resolvers, sections, helpers organized into folders
