/**
 * 02 – Main mirror workflow.
 *
 * Walks through the full first-time user journey:
 *   1. Create Gitea admin user + API token
 *   2. Create the mirror target organization
 *   3. Register / sign-in to the gitea-mirror app
 *   4. Save GitHub + Gitea configuration
 *   5. Trigger a GitHub data sync (pull repo list from fake GitHub)
 *   6. Trigger mirror jobs (push repos into Gitea)
 *   7. Verify repos actually appeared in Gitea with real content
 *   8. Verify mirror job activity and app state
