/**
 * Covers migration 20260808150000_shopify_connections:
 *   1. RLS: members insert and read their own company's connection,
 *      non-members see nothing and cannot insert for a foreign company.
 *   2. One ACTIVE connection per company (partial unique index).
 *   3. One store actively connected to at most one company.
 *   4. No DELETE policy: a member DELETE silently affects zero rows.
