Update service files to get apiClient and config from App singleton
Update entrypoint index.jsx to use App event handlers and initialize function
Update access to "authentication" data that was in redux, but isn't anymore.
Use frontendAuthWrapper helpers
Remove common and components folders, folding anything not in frontend-base into the app's main page module.
Update tests so they work again.
Update dependencies to satisfy frontend-base minimum versions.
Refactor Header and Footer into a fully encapsulated Component if frontend-component-header and frontend-component-footer aren't ready for use yet.
Have the main page module export a "Main" component around the Page component as necessary, if it's using the router. (See frontend-app-profile for an example of how PageContent became ProfileMain and the Header/Footer moved up to the top-level index.jsx file)
Cease to use connected-react-router if it's being used.
This list may not be exhaustive, sadly.
We are NOT going to adopt frontend-config right now. This ticket will stop short of doing that.
