style(settings): center the About section on the page

AboutInfoView (icon/name/version/links) now centers both
horizontally and vertically within the detail pane instead of sitting
pinned to the top-left like the other sections. Needed a GeometryReader
+ minHeight on the shared ScrollView wrapper — a ScrollView proposes
unbounded height to its content, so maxHeight: .infinity alone doesn't
give short content anything to center within; minHeight pinned to the
real viewport height does. Harmless for the other sections, which stay
top/leading-aligned as before.
