/**
 * ViewSettingsPopover
 *
 * UX Sprint 2 (P1-4): consolidates four small toolbar controls that the
 * UX audit flagged as "too many top-level chips":
 *   - Group by
 *   - Row color
 *   - Density
 *   - Hide fields
 *
 * into a single "View settings" popover keyed by a gear icon. Filter and
 * Sort remain top-level because they're primary data operations, but the
 * appearance/grouping cluster collapses behind one trigger that opens an
 * accordion-style sheet.
 *
 * Implementation notes:
 *   - Each section is collapsible (default open) so users can focus on one.
 *   - Content is duplicated from the original inline popovers; if you change
 *     behavior, update both this and the legacy code path in ListView.tsx
 *     (kept behind `appearance.compactToolbar: false` for back-compat).
 *
