Address e2e review feedback

- Add ENABLE_CAPTCHA=false to CI app.ini so the server starts with
  CAPTCHA disabled instead of relying on env var in test script
- Retry on 502/503 in addition to 500 in apiRetry helper
- Fix typo: workarkound → workaround
- Add comment about section-unaware INI parsing in test-e2e.sh
