 * Verifies that the eleven Category-A tables use Crockford ULID primary
 * keys, not integer auto-increment. Split into two groups:
 *   - Model-backed tables (A-05/06/09/10/11): check HasUlids + ULID shape
 *     + Route::bind resolves via implicit model binding.
 *   - Pure pivots (A-01..A-04): DB-level check that two inserts produce
 *     distinct, 26-char, Crockford-sortable ULIDs.
