resolves #3282

What is in this change?

• Allow the manager role to view the models in a dropdown while on workspace settings.
• Additional security on customModels to only persist a passed ApiKey when the role is null (no auth mode) or the role is explicitly ROLE.admin. null role is okay here since to get to this function the middleware does the proper auth checks.

TODO:

• If I am a manager and I attempt to pick an LLM that has not been configured, the credential modal should not appear since that update will fail and the details will not persist.
