how do i make sure the timeline bar of @frontend/components/messages/MessageList.tsx takes up the entire height of the list + 48px (24px on top, 24px on bottom) while `isNested`?\

I will adjust the timeline bar CSS in `frontend/components/messages/MessageList.tsx` to ensure it extends correctly when nested.

I will modify the styling logic to:
1.  Remove `h-full` from the base classes.
2.  Add `h-full` only to the non-nested state.
3.  Use `-inset-y-6` (which sets both top and bottom to -24px) for the nested state, removing the `bottom-0` override.

This will allow the timeline bar to stretch 24px above and 24px below the container height when `isNested` is true.

I've updated `frontend/components/messages/MessageList.tsx` to handle the timeline bar height as requested.

When `isNested` is true, it now uses `-inset-y-6` (without `h-full` or `bottom-0`), which makes the bar extend 24px above and 24px below the container.
