The Gitea create-issue path (server route, client, wire api, facade, UI
button/dialog) landed with the forge user-lookup work; close the remaining
verification/documentation gaps:
- wire: gitea.test.ts covers issueCreate (POST /api/gitea/issues/create,
full/optional body, error throw)
- docs: DOCUMENTATION.md lists createIssue client method and the
POST /repos/{owner}/{repo}/issues endpoint (labels as names)
- ui: fix stale 'read-only by design' JSDoc in GiteaIssuesSection — creation
is offered here and the detail view provides edit/close/reopen
