fix: repair 3 failing tests after page/component extraction

- DashboardPage.test.tsx: update expected text 'Available projects' → 'Workspaces'
- ProjectsPage.test.tsx: add project.description rendering to ProjectCard
- repositories-settings-tab.test.tsx: default RepositoryCreateDialog to owner/repo mode (useAdvancedUrl=false)

Quality gates: all 80 tests pass
