[v11.0/forgejo] fix: make API /repos/{owner}/{repo}/compare/{basehead} work with forks (#8333)

**Backport:** https://codeberg.org/forgejo/forgejo/pulls/8326

- fix: make API /repos/{owner}/{repo}/compare/{basehead} work with forks
- add test coverage for both fixes and the underlying function `parseCompareInfo`
- refactor and improve part of the helpers from `tests/integration/api_helper_for_declarative_test.go`
- remove a few wrong or misleading comments

Refs forgejo/forgejo#7978

Note that this is a partial backport for reasons explained at https://codeberg.org/forgejo/forgejo/pulls/8326
