refactor: move `token_status_list.rs` from API layer to core

### Description

Move the serve token_status_list logic to the issuance domain.

Business logic shouldnt live in the API layer, since UniCore is set up in a way it should be able to be implemented not only via https but also other methods (grpc, event streaming etc.)

### Resources

_No response_

### To-do List

- [ ] Move the serve token_status_list logic to the issuance domain
