fix: standardize spacing in SessionSummary component

Replace inconsistent marginBottom with marginTop for section headers
and remove unnecessary margins from content boxes. This creates more
uniform spacing between sections by applying top margin to headers
instead of bottom margin to preceding elements.

Changes:
- Remove marginBottom from "Interaction Summary" header
- Change "Performance" header from marginBottom to marginTop
- Remove marginBottom from "Tool Time" box
- Change "Resources" header from marginBottom to marginTop
