changes needed for setting up dev Okta account

[thetif]

Description

Due to changes in the project, we want to make sure the code is as open source as possible. One of those current blockers is needing an Okta account. This PR is updating things needed to follow the new instructions for creating a dev Okta account, which is free for devs trying to learn Okta or using Okta for personal development reasons.

The main change is adding an new environment variable for OKTA_AUDIENCE and updating it in all the places that need to change to add an env.

I also added a few more test users and changed the seed to use Pending Admin instead of State Admin for the Federal Admin panel tests.

Steps to manually verify this change

1. Login and log out as a couple of the shared accounts
