Note

Refines EVM token approval handling to improve Rango swap reliability, especially for non-standard tokens like USDT.

• In defiUtils.ts, adds pendingTxs: [...out] to EdgeSpendInfo when creating approval spends so sequential approvals (e.g., reset-to-0 then set) are chained properly
• In rango.ts, uses evmTransaction.txTo as the approval spender (recipientAddress) instead of approveTo, ensuring approvals target the actual swap contract
