Move /source/views/components to /source/components

[hawkrives]

There are a lot of changes here, but they're all of this form:

- import type {NavType} from '../../types'
+ import type {NavType} from '../../views/types'

So! This is part of a refurbished, repolished #1537 (the giant reorganization PR). That one tried to do three separate things (move components/ to the top level, reorganize app initialization, and restructure the app views); I've decided to break the changes into smaller chunks for review 😸

This PR just moves the components/ folder to the top of source/ (this will make more sense once I move things out of views/, which will happen. Maybe even today.).

Flow doesn't complain about these changes, and the app still builds in manual testing.

Timeline

• Move components to source/
• Rename flux/ to redux/
• Reorganize app initialization
• Set up things to we can do import … from '@app/components/colors' instead of import … from '../../../../components/colors'
• Extract reusable views from views/ into modules/
• Automate-ish the loading of views from views/ and deprecate the views.js object
