fix: Reconnect Auth Fail Fix - embed-widget

[AkshatJawne]

Resolves #1256

Changes Implemented:

• Refactored disconnection, shutdown, and auth fail handling logic to now be ConnectionBootstrap in order to properly handle auth fail event in the embed-widget

Visual of modal that appears on auth fail:

I also noticed this doesn't stop listening when the server is shutdown which is different behavior than what we currently have. I tested this by just stopping/starting the core server. The app showed the "auth failed" modal in that case. Previously this would just stay on the "Server shutdown" component.

@mattrunyon Have been testing on my local branch, not able to reproduce, when I shut down the core server and start it again, I do not see the "auth failed" modal, it just stays on the "Server shutdown".

Changed test case based on new logic, until the connection is resolved, it will show the modal, and hence for the first assertion of the connection bootstrap, should not be null.

Will still need @mofojed to review again. I want to make sure he's ok w/ the state names as well.

Changes for the states could be not_connecting -> errored. And failed -> authFailed instead. I'm indifferent though
