Pull Request Overview

This PR adds multichain wallet management support to the iApp CLI, enabling operations on non-gasless chains like Arbitrum. The implementation includes encrypted wallet storage, transaction confirmation prompts, and balance checking to improve user experience and security.

• Replaces private key-based wallet handling with a comprehensive wallet management system
• Adds support for experimental networks (starting with Arbitrum Sepolia testnet) behind a feature flag
• Implements balance verification and transaction fee warnings for non-gasless chains

Why continue generating a random wallet during project initialization, even if the wallet will be empty and unusable on Arbitrum?

We want the process to be as easy as possible on bellecour, which will be the only free sandbox environment.
Generating the wallet allows us to not bother the user with importing private keys until we need a funded wallet.
