/**
 * LT-INT-series: list-title catalog + numbering (Fase 18).
 *
 * Validates the role gate on `add_list_title` / `remove_list_title` (the
 * only role-gate path pgTAP can't cover because postgres bypasses
 * auth.uid). Also exercises the suggestion union + the per-collective
 * numbering math directly against the dev DB so the SQL `or(...)` filter
 * and the client-side parser stay in lockstep.
 *
 *   LT-INT-01 admin add → suggestions include the new title
 *   LT-INT-02 member add → P0002
 *   LT-INT-03 computeNextNumber with 3 lists "Compra #1/#2/#5" → 6
 *   LT-INT-04 computeNextNumber with no matches → 1
 *   LT-INT-05 admin remove → row gone, suggestions exclude it
 *   LT-INT-06 add empty title → P0001
