User Entity

[Scot-Survivor]

Before login can even begin a user entity must be designed.

Due to reflecting the jellyfin api, we can use JellyFin's entity models as a good starting ground.

However as long as the api translates fields it won't matter.

I'll hop right on this, and begin translating some entities. Will also likely need a @RestController for handling Auth, so AuthController.

With fallback to /login slug mapping (or jellyfin API equivalent) when user not authorized.

#12 for the controller, entity is likely required first.

It's all decoupled anyway.
