Review and adjust the margins on the summary component

[rmccar]

As a user,
I want the margins on the summary component to be reviewed and adjusted,
so that the margin bottom on the group title is changed from 16pix to 8pix, providing a more compact and visually appealing layout.

Acceptance Criteria:

1. Investigate the current margin settings on the summary component.
2. Identify the margin bottom setting on the group title.
3. Change the margin bottom on the group title from 16pix to 8pix.
4. Verify that the changes are consistent across different screen sizes and devices.
5. Ensure that the visual appearance of the summary component is improved and aligns with the overall design guidelines.
