Review all secrets across all DCAs

[ychae]

Describe the bug
Need to review all secrets and identify:

1. Time out of secrets and how do we update them
2. Who owns them (e.g. service accounts)
3. What types of secrets are currently stored

This is likely the cause of users logging in as themselves and seeing someone else's username in the dashboard

To Reproduce
Steps to reproduce the behavior:
Unknown yet, haven't been able to reliably reproduce the error

Expected behavior
Need to make sure that all secrets remain up to date and correct. And also ensure that the username that shows up on the dashboard is the same as the username of the person that has logged in.

Screenshots

During demo testing, @milen-sage and I were testing the DCA dashboard, this is a screenshot of @milen-sage's view where he was logged into his account but saw my username in the dashboard instead.

Additional context
Add any other context about the problem here.

I just logged into the data curator demo and saw my username in the dashboard as expected 🤔

We've noticed that it tends to happen if two folks are using the same app at the same time, but we couldn't identify the exact sequence to get it to repro 😭

Related to #341; partially redundant but has a specific instance of secret mishandling (likely resolved in latest releases of DCA, but will keep open to confirm).
