The pinned 'Overview' sidebar entry used a rounded, inset pill (margin +
border-radius:8px) so its hover/active highlight floated in the middle of the
sidebar, unlike the full-width app-category rows below it. Drop the margin and
radius, adopt the .category padding (15px 20px), border-bottom separator and
var(--surface-hover) hover, so the highlight spans the full sidebar width with
square corners and matches the categories. Keeps font-weight 600 + the
page-updater active tint as its only distinguishing marks.
