Preserve Loader2 props and test the loading contract.

This mock drops className and other props, so tests cannot catch regressions to animate-spin or aria-hidden. Forward SVG props and add assertions for aria-busy="true" and the loading labels for both buttons.

Proposed mock improvement

-  Loader2: () => <svg aria-hidden="true" />,
+  Loader2: (props: React.ComponentProps<'svg'>) => <svg aria-hidden="true" {...props} />,

Superseded duplicate Palette UX/terminology/loading cohort. Close to drain PR queue; re-land single focused PR if still needed on develop.
