fix(ci): give AVM check-circuit more CPU/timeout so large txs don't time out

+  # within 30s when capped at 2 CPUs, so they time out (exit 124). check_circuit parallelises over
+  # rows, so we give each container 4 CPUs to roughly halve the check time plus a larger timeout for
+  # headroom. With `parallelize 16` this is 16*4 = 64 CPUs, matching the smallest CI fleet instance
