[Front/Back] Credit Management System

[its-colby]

• Allow an admin route to the backend for granting permissions (upload/download tier levels) to OIDC registered users
• (back) Create a database for users that keeps track of their amount uploaded/downloaded and their monthly limits
• (back) Ensure that any upload/download requests to the server are allowed AKA the user has a proper auth token and hasn't reached their limit
• on the frontend, ensure there is a profile component where the user can see how much of their allotted upload/download they have used and what kind of plan/tier/subscription they are on.
• add api keys to work with credit management system for SDKs
