Separating authorized and non authorized endpoints and use middleware

[112batuhan]

like talked with @aticie , to utilize middleware and have better status code (currently unauthorized users return 422, which should be 401 forbidden) when users are not authorized, we will split the api into two fastapi instances. One will be used to serve unauthorized endpoints, other will serve authorized ones.

Instead of this, It's better to use dependencies like we do now. I was too axum pilled.
