Method send

lib/TransactionKit.ts:1833–2453

* Estimates and sends the currently selected transaction. * * This method validates the current transaction context, estimates, and submits the transaction using: * - modular mode: the Etherspot Modular SDK batch and send flow * - delegatedEoa mode: viem account abstraction with EIP-7702
