Closes #524

Enable screenshots, video recordings, and traces on E2E test failures in the Text Editor, Diagram Editor, and Dual Editor Playwright configurations. The existing CI artifact upload step collects these files to help debug failing tests.

This PR contains only the three playwright.config.ts changes. Artifact generation and upload can be verified using the intentional failures in the companion PR #529.

How to test:

1. Open the CI run. In Artifacts, download and extract playwright-ubuntu-latest.

2. Locate the failed-test folders under:

   • open-workflow-diagram-editor/test-results/
   • text-editor/test-results/

   For each intentionally failing test, verify that the folder contains:

   • test-failed-1.png
   • video.webm
   • trace.zip

3. Open each screenshot and play each video.

4. Open Playwright Trace Viewer and drag in one trace.zip at a time, keeping it zipped. Repeat for both tests.

5. Repeat steps 1–4 with playwright-macos-latest and playwright-windows-latest. All artifacts can be inspected on your local machine, regardless of the runner OS.

Expected result: screenshots, videos, and readable traces are available for both intentional failures on all three operating systems.
