[One Workflow] Fix Actions menu row layout after EUI 116 upgrade

EUI 116 routes EuiSelectableListItem through the shared EuiListItemLayout,
which adds vertical padding on __text and a gap on __content.
renderActionOption owns its own spacing, so the new styles stacked on top
and inflated every row. Zero out the gap/padding to restore the row height.
