Ignore gas when zkauth

[Mdaiki0730]

Description

zkauth uses a ephemeral key to perform tx signature and includes zkauth signature in msg.

• Ephemeral keys do not have the ability to pay fees, so ignore DeductFeeDecorator when zkauth is included.
• It is originally necessary to subtract the fee from the zkauth address, but I will leave this as a todo and temporarily decide that the fee will not occur.
