Console should automatically perform login redirect for unauthenticated users

[schottra]

Motivation: Why do you think this is important?
When hitting FlyteConsole for the first time, users are often immediately presented with a dialog letting them know they need to log in. The original purpose of this dialog was to support an edge case of being able to refresh credentials for a user without having to leave an already rendered view. But the current implementation is just a placeholder for being able to do the login flow in a separate tab. The more common case is that users are forced to do an additional click when they are loading the app for the first time after credentials expire. This is unnecessary and a little obnoxious.
For now, we should remove the intermediate dialog and just do the authentication redirect immediately.

We can add a separate issue to support redirect-less credential refreshes later on.

Goal: What should the final outcome look like, ideally?
User does not need an additional click to perform the login flow when loading Flyte Console.
