UI: Ember deprecation - addObject, removeObject (#25952)

* Update add-to-array and remove-from-array helpers

* Replace add/remove object in MFA files - All MFA tests pass

* Replace in PKI components (pki tests all passing)

* Replace in core addon where applicable

* glimmerize console service -- console tests pass

* more replacements

* update string-list, add comment to vertical-bar-chart

* Refactor CSP Event service

- only used one place (auth-form) so simplified that usage
- glimmerize and refactor so that the tests work

* small updates

* more cleanup

* Fix tests

* Remove objectAt from console-helpers

* Address PR comments

* move commandIndex clearing back

* Remove extra model set
