NYM-1199: Add visual flow report for Node Families E2E tests

Enhances Playwright E2E tests by capturing full-page screenshots at each
journey step, which are then stitched into a static `e2e-report/index.html`
filmstrip.

This report is uploaded as a CI artifact (even on failure) to provide a
visual overview of test execution, aiding in the detection of UI regressions
and expediting debugging of test failures.
