Set API keys via UI instead of .env

The title says it all. It would be a cool feature to have some sort of input forms on the onboarding and settings page to set the necessary API keys instead of using .env.

I'm not very familiar with environment variables, but since the application is meant to be used locally, I think you could make the API connection easier for novice users by giving it an interface. Along with this, you could test the functioning of the API keys once inserted by contacting the endpoints to prevent possible errors due to missing keys.

I like this idea from a UX perspective, but we would likely have security concerns with it.
