Missing `receive()` function in `MondrianWallet2` makes it impossible for the wallet owner to directly receive Ether.
Description
The receive() function would allow a smart contract wallet to accept plain Ether transfers. Meaning that when someone sends funds directly to the contract's address the receive() function is invoked. However, MondrianWallet2.sol does not implement the receive() function, nor a fallback() function.
Impact
The absence of the receive() function in MondrianWallet2.sol would prevent the smart contract wallet from accepting plain Ether transfers directly to its address, leading to failed transactions and potentially causing disruptions in services that rely on direct Ether transfers.
