Fix visual smoke test for DevAI Systems Portfolio

[arii]

Fixes the failing visual comparison for research smoke test.

The test tests/visual.spec.ts was timing out because it was waiting for a heading with the text /DevAI Portfolio/. However, the actual text rendered by the component is "DevAI Systems Portfolio".

This commit updates the test assertion to expect the correct text, allowing the test suite to pass. Baseline screenshots have also been updated to reflect the new state.
