feat(audit): Batch 19 — Settings information architecture (UX7, UX8, UX23)

UX7: 11 cards grouped into five sections (Downloads, Appearance,
Network & accounts, Advanced, App & maintenance) with section headings
and a jump nav under the search box; search hides empty sections and
the nav; heading hierarchy corrected (h1 page, h2 section, h3 card).
UX8: post-processing card co-located under the Downloads card and
renamed 'Post-processing' with a defaults-vs-advanced hint.
UX23: closed as stale duplicate of the already-fixed L71 (editable,
validated, reconciled folder inputs) — verified in the preview probe.
