fix(test): resolve CI timeout in webseed-playback e2e test

- Switched from `waitUntil: 'networkidle'` to `domcontentloaded` + explicit selector wait to avoid flakiness from background polling.
- Added fail-fast logic to detect "Failed to load content" view states.
- Added error logging to capture page state if the test times out.
