[Bug]: Extension is using an over-estimated gas value to gate submission of a Swap txn

[a-breslin]

Describe the bug

The Swaps team has identified an issue where the Mobile and Extension clients are overestimating gas costs in the Swap UI.

On Mobile, this should only require a backend change to resolve, but on Extension, we need to make a small change to the logic that determines which gas estimation is used to deactivate the Swap button/CTA. @micaela.estabillo has prepared a very small PR here (in review), which we will likely need to CP into the 13.13.0 RC tomorrow.

Expected behavior

Swap CTA/button should be deactivated only when the user's amount of native gas tokens held is less than required to submit the transaction.

Screenshots/Recordings

No response

Steps to reproduce

1. Go to swap and fetch a quote on Ethereum/an EVM
2. Notice higher than required gas estimation in the Network Fee line in the quote card
