fix(init): replace paddingRight with gap on split pane row

The paddingRight={1} on the left ActivityPane column caused
inconsistent left-side spacing when the prompt was active vs
dismissed — Ink's flex recalculation shifted content. Using
gap={1} on the parent row instead spaces the panes evenly
without affecting the content area width.
