Remove the feature of "cross-chain transfers with calls" for consumer, this feature can be provided by Helixbox

[hackfisher]

For the need to handle cross-chain transfers with calls, the following product combination can provide a solution, which is fully compatible with the future Helixbox Smart Account and Intent products:

A combination of Smart Account (gas-less paymaster) + Smart Account signatures (chain-agnostic, enabling chain abstraction) + Helixbox Bridge/Cross-chain Swap.

The UX needs adjustments to abstract away the concept of chains, unifying the generation of consistent Smart Account addresses across chains and displaying user assets in an asset-centric view.

When users need to make a cross-chain call (where the asset and chain call are on different chains), they initiate two Intents:

1.	One Helixbox Bridge Intent
2.	One target chain conditional paymaster Intent/signature.
