feat: add resetNetwork option to WalletManager

[drichar]

Description

This PR enhances the WalletManager by introducing an options object in its configuration. The first option implemented is resetNetwork, which allows users to reset the network to the configured value on each initialization, overriding any persisted network state.

const walletManager = new WalletManager({
  wallets: [...],
  network: NetworkId.TESTNET,
  algod: {...},
  options: {
    resetNetwork: true  // App will always start connected to TestNet
  }
})

Details

• Added options object to WalletManagerConfig interface
• Implemented resetNetwork as the first option in the options object
• Updated WalletManager constructor to handle the resetNetwork option
• Added and updated tests to cover the new resetNetwork behavior
• Ensured backward compatibility with existing configurations

This change provides a flexible framework for adding more configuration options in the future, while addressing the immediate need for network reset functionality. The resetNetwork option, when set to true, allows applications to enforce a specific network configuration.
