wrong & missing return for `/evm/transactions` endpoint

[8times4]

Hey Team,

It seems like the raw output vs openapi schema does not align for sim.

The endpoint also returns gas_used, effective_gas_price and success, while the spec defines max_fee_per_gas, max_priority_fee_per_gas (which are not being returned) and also no success attribute is defined.
While I understand that the spec has those max_* returns as optional and IIRC I have seen them existing in Echo in the past, the success seems like the most crucially missing attribute here.

Also might be an oversight to double return the same value with gas_price and effective_gas_price:

Thanks,
