chore(issues): point the issue chooser at this repo, not upstream Cinny

The forked-in Cinny issue setup funneled reporters to the upstream project:
- config.yml disabled blank issues and linked to cinnyapp/cinny GitHub
  Discussions
- preapproved.md was Cinny's "do not open an issue, use Discussions"
  template (Gitea has no Discussions anyway)

Replace it with a Lotus setup: enable blank issues, drop the upstream
contact link, and add Bug Report + Feature Request templates. Now
/issues/new/choose offers Lotus templates and files against this repo.
