 * Wait until all `expectedUserIds` show up as matching `expression` via the

 * Why this exists: ABAC queries (validateExpressionAgainstRequester,
 * calculateMembershipChanges) read from a Postgres materialized view
 * (`AttributeView`). The enterprise access-control service refreshes that view
 * at most once every 30 seconds — so freshly-written CPA values are not visible
 * until the next refresh tick. A test that writes a brand-new CPA value and
 * then immediately clicks "Save" on a rule referencing that value will hit
 * `requester_matches: false` and surface the self-exclusion modal instead of
 * the membership-changes confirmation modal.
 *
 * Polling forces wall-clock time to advance; the next CEL query after the 30s
 * gate elapses will refresh the view and pick up the new attribute values.
 * Default timeout 45s = 30s gate + 15s headroom.
