fix: bypass Gitea 1.26.2 false-failure bug for deploy job

Gitea 1.26.2 reports job conclusion=failure even when all steps succeed,
causing the deploy job (with needs:) to be skipped. Two fixes:
- Add if: always() to deploy job so it runs regardless of test job conclusions
- Fix concurrency: YAML structure (was nested under on: instead of top-level)
