[Bug]: Swap network fees not always accurate

### Describe the bug

Issues
- effective gas fees are used to gate tx submission (these are lower than the actual required gas amount)
- when gas is included in the quote, the network fee estimates are shown instead of the estimates provided by the backend

### Expected behavior

The totalNetworkFee should gate tx submission. `includedTxFees` should be shown when submitting a gasIncluded trade

### Screenshots/Recordings

### Steps to reproduce

1. Request EVM quotes

### Error messages or log output

```shell

Start by tracing the EVM quote request and gasIncluded trade submission flow in the mobile app. Verify that totalNetworkFee gates transaction submission and that includedTxFees is displayed for gasIncluded trades; reproduce with an EVM quote to confirm the corrected behavior.
