fix: update WelcomeModal and QuickstartInitialView tests for new flow

- WelcomeModal: "Load workflow" now navigates to WorkflowBrowserView
  instead of calling browse-directory API directly. Replaced 4 obsolete
  fetch-based tests with 3 tests covering view navigation and callback.
- QuickstartInitialView: updated description regex to match new copy
  ("generative AI pipelines" instead of "AI image generation").

All 1934 tests now pass.
