Send To Device Support (#1557)

* Tweaked the logging output

* Started implementing some basic idea for devices

* Updated Email Service with new API routes

* Implemented basic DB structure and some APIs to prep for the UI and flows.

* Added an abstract class to make Unit testing easier.

* Removed dependency we don't need

* Updated the UI to be able to show devices and add new devices. Email field will update the platform if the user hasn't interacted with it already.

* Added ability to delete a device as well

* Basic ability to send files to devices works

* Refactored Action code to pass ActionItem back and allow for dynamic children based on an Observable (api).

Hooked in ability to send a chapter to a device. There is no logic in the FE to validate type.

* Fixed a broken unit test

* Implemented the ability to edit a device

* Code cleanup

* Fixed a bad success message

* Fixed broken unit test from updating mock layer
