no issue
Automated tools, code generators, and editor integrations are increasingly standardising on the import style used in `ember-modules-codemod`. Our import style differed a little with regards to service/controller injection imports which meant we were starting to see inconsistent naming.
no issue
- add eslint-plugin-ember, configure no-old-shims rule
- run `eslint --fix` on `app`, `lib`, `mirage`, and `tests` to move imports to the new module imports
- further cleanup of Ember globals usage
- remove event-dispatcher initializer now that `canDispatchToEventManager` is deprecated
no issue
- moves general UI state control such as menu display, autonav, settings menu, etc into a `ui` service for easier use within components
- no longer required to jump through hoops passing state and actions down from application controller into components
- removes indirect "route" actions in favour of calling actions/methods directly on the `ui` service
