The issue:

1. Story

As a Forgejo developer,
I want that I can succinctly express public or private issue identity,
so that function calls and intermediary data structures are clear and concise.

1. Acceptance Criteria

• [ ] Internal APIs using issue IDs (integer numbers corresponding to DB primary keys) are converted to pointers to `Issue` structs.

1. Background

In many places in the code, numerical IDs of issues are used to identify them. With private issues stored in a separate table, the ID values don’t identify issues uniquely anymore. [Gusted commented in favor of this](https://codeberg.org/forgejo/design/issues/2#issuecomment-8405379) in the design ticket.
