/**
 * v1.16.10 — the "Medikamente" settings section (`/settings/medications`).
 *
 * Hosts the /medications list customisation following the dashboard /
 * insights pattern: the cards ⇄ table view preference (the shared header
 * toggle, optimistic PUT) plus the manual-order editor INLINE (two
 * grouped sections, explicit Save). SSR smoke assertions, matching the
 * rest of the settings suite — the editor's interactive contract is
 * pinned in `medication-order-editor.test.tsx`, the PUT side in
 * `use-medication-list-layout.test.ts`.
