refactor(notes): restore fixed mobile heights for scroll math

Re-pin .note and .stacked-note to 100dvh on mobile and bring back the
container height in useResizeContainer so (index + 1) * height has a
reachable scroll target. Switch the polled scroll helper to that same
formula instead of offsetTop.
