/**
 * SA-series — Server administration UI (Fase 13.5.2).
 *
 *   SA-01 Ana (seed admin) sees the /admin link in the sidebar and can reach
 *         /admin/collectives. Borja (member) does NOT see the link, and
 *         visiting /admin directly redirects to /.
 *   SA-02 Admin soft-deletes a throwaway collective via the UI, then restores
 *         it. The status badge flips deleted ↔ active. The audit log page
 *         lists both actions.
 *   SA-03 Admin promotes Carmen to server_admin from /admin/admins; the entry
 *         appears in the list. Then revokes her. Trying to revoke the sole
 *         remaining admin is blocked by the server-side guard and the UI
 *         surfaces an error (without breaking the page).
 *   SA-04 Admin sets a server-level default-section override OFF for "notes"
 *         from /admin/server; a member of the seed collective who had notes
 *         ON locally sees the section disappear from their nav within a
 *         reload (no realtime on server_settings — acceptable; the page
 *         re-evaluates on next mount).
 *
 * Idempotency: every test creates its own throwaway collective via direct
 * SQL through the in-page Supabase client (`__sb`). The afterEach clears it.
 * Promotion state for Carmen is rolled back via direct DELETE.
