fix: prevent tall images from being cropped in live-preview wrapper

The wrapper used inline-block for tools without overlay children (e.g.
border). CSS maxHeight: 100% on the img inside an inline-block parent
without explicit height does not resolve, so tall images rendered at
natural height and got clipped by overflow: hidden. Unify both code
paths to always use inline-flex + column, where the flex item properly
shrinks within the container's maxHeight constraint.
