fix(ui): truthful uninstall progress bar (was a solid full-red block)

AppCard's uninstall bar was hardcoded `w-full bg-red-400/60 animate-pulse`
— a solid, full-width, red, fake-pulsing block that never moved and read
as an error, no matter the actual teardown progress (the install bar, by
contrast, renders a real percentage). Derive a truthful percentage from
the backend's existing `uninstall-stage` label — "Stopping containers
(X/N)" → 10–50%, "Cleaning up volumes" → 70%, "Removing app data" → 90%
— and render it exactly like install: neutral fill, real width + percent,
shimmer (not a fake pulse) carrying motion when a stage has no number.
Frontend-only; the backend already broadcasts these stages.
