test(traces): add MSW data-render tests for grouped and list views

Swaps ResizeTable for the shared TracesTable, so the grouped view gets
resizable and reorderable columns persisted per-device via
TRACES_VIEW_COLUMNS. Keeps prev/next pagination; the toolbar now always
renders so pagination doesn't disappear on an empty result.
