Test exact intrinsic gas boundary including auth state gas.

The intrinsic cost includes regular gas (G_TRANSACTION + G_AUTHORIZATION per auth) and state gas ((STATE_BYTES_PER_NEW_ACCOUNT + STATE_BYTES_PER_AUTH_BASE) * cpsb per auth). With gas_delta=0 the tx has exactly enough and succeeds. With gas_delta=-1 the tx is 1 gas short and is rejected as intrinsic-gas-too-low.
