test+style: fix 2 full-suite regressions from the channel edits

- test_api_timeout: assert the updates/check call keeps timeoutMs:60000 in its
  new _checkBody form (functionally identical; still the 60s override)
- panels.js: reword two // comments to drop apostrophes — the smooth-text-fade
  brace-matcher test treats ' in a comment as a string delimiter and lost
  loadSettingsPanel's closing brace (node --check confirms the JS was always valid)
