SELFDESTRUCT to an empty beneficiary with balance charges ACCOUNT_WRITE.

The destructor has a non-zero balance and targets an empty, non-existent beneficiary, so the net-new ACCOUNT_WRITE applies: execution = OPCODE_SELFDESTRUCT_BASE + access + ACCOUNT_WRITE. The creation gas GAS_NEW_ACCOUNT is charged on the state axis (the EIP-8037 suite asserts it); here it is funded from the reservoir and the value transfer to the new beneficiary confirms the path.
