ci: make merge-reports-to-TestDino non-blocking for playwright_summary (#11457)

## Summary

- In `playwright_summary`, `merge_and_upload_reports` result of
`failure` is now treated as non-blocking (same as `success`/`skipped`)
- The Playwright summary check will pass even if the TestDino
merge/upload job fails (e.g. network issues, bad token, API outage)
- Actual test results (`build_binary`, `ui_integration_tests`) still
gate the summary as before

## Why

The TestDino upload is observability/reporting infrastructure — it
should never cause a PR's required check to fail when the tests
themselves passed. Previously a transient TestDino failure would block
merges.

## Test plan

- [ ] Verify `playwright_summary` passes when `merge_and_upload_reports`
succeeds (existing behavior)
- [ ] Verify `playwright_summary` passes when `merge_and_upload_reports`
fails (new behavior)
- [ ] Verify `playwright_summary` still fails when
`ui_integration_tests` fails (unchanged)
