fix(wallet): detect counterfactual wallet gas simulation failure in send-native

When a smart wallet hasn't been deployed on-chain yet, the Sequence relayer
fails gas simulation with 'Request aborted'. Previously this gave a cryptic
error. Now both fee paths detect simulation failures and surface a clear
actionable message telling the user to fund the wallet with USDC first.
