Description

Add a gaslessTransfers flag to the no-modal SDK account-abstraction config.

• Dashboard smartAccounts.gaslessTransfers is copied into accountAbstractionConfig.
• Constructor accountAbstractionConfig.gaslessTransfers overrides the dashboard value.
• Init throws if gaslessTransfers is true without MetaMask smart account type and EIP-7702.

How has this been tested?

• Lint for @web3auth/no-modal.
• noModal.test.ts gasless config cases passed in Chrome and Safari.

Test plan

• Init with dashboard gaslessTransfers: true and MetaMask EIP-7702. Config is true.
• Init with constructor gaslessTransfers: false and dashboard true. Config stays false.
• Init with constructor gaslessTransfers: true when dashboard omits the flag. Config stays true.
• Init with gaslessTransfers: true on Safe / EIP-4337 throws WalletInitializationError.

Note

Medium Risk
Touches SDK account-abstraction initialization and validation; misconfiguration now fails fast at init, and gasless mode depends on MetaMask EIP-7702 plus wallet-services integration.

Overview
Adds gaslessTransfers to no-modal account-abstraction config: dashboard smartAccounts.gaslessTransfers is merged on init, constructor values override the dashboard, and init throws unless the setup is MetaMask + EIP-7702. Types and tests cover merge/override and invalid combinations.

The vue-app-new demo is extended to exercise this: settings for EIP standard (4337 vs 7702), gasless transfers, and local wallet services (localhost:4050); AA options pass smartAccountEipStandard and gaslessTransfers, omit per-chain bundler config for 7702, and still apply wallet-services confirmation when gasless is on without the widget button. The dashboard adds ERC-20 transfer testing (defaults per chain, e.g. Arbitrum 0xa4b1).
