For the fully gasless flow, do we need to update submitViaRelayExecute in relay-submit to use the accountOverride also since it would be providing the funds?

This should also already work as from is now updated in quote.

This flow just uses the transaction and not from so I think we need to fix this manually.

Can do in a separate PR if easier, but for the withdraw flows, if we have a accountOverride, then we want that to sign the withdraw transaction rather than the original from.
So do we need to convert the withdraw transaction data to delegations on line 353 of relay-submit.ts?

This is also a special case as while the data is currently using the original from via transaction which is what we want, we now need to convert it to delegations with getDelegationTransaction so our accountOverride can submit it.

Slightly ambigious as the delegation is still done on behalf of the original from and not accountOverride. Plus this also still applies when isPostQuote is true.

Valid point, I updated the PR
