ref(crons): Fix spacing between env labels and timeline (#57862)

Spacing here regressed with changes to the timeline view, such as adding
the action menu (`...` button) to delete individual environments

Fixed:
- Padding around `Show X More` button
- Timeline now properly aligned with environment label
