Fix CommandPalette test for Spotlight rebuild

The Spotlight rewrite widened the palette to search projects, saved queries,
visualizations, and dashboards — and updated the placeholder text accordingly.
The test still expected the old 'Search projects...' placeholder and didn't
mock the three new API modules, so the calls to getSavedQueries /
getVisualizations / getDashboards triggered real network requests in jsdom.

Updated the placeholder assertion to match the new copy (regex-based for
robustness to typographic punctuation) and added vi.mock entries for the
three additional API modules.
