fix(test): add RPCEVMTimeout override to executecodec_test and fix import ordering

Add the same RPCEVMTimeout: 60s override to executecodec_test.go that
msghasher_test.go already has. Both tests call eth_call through the
simulated backend and are subject to the default 5s timeout under
-race -count=100. Also fixes time import ordering per review.
