Pull request overview

This PR fixes unwanted switchChain requests during EVM wallet connection by introducing a defaultNetwork configuration option that allows developers to specify the initial network for connection, preventing unnecessary chain switching.

Key Changes

• Added defaultNetwork to OptionsController state to store the user's desired initial connection network
• Renamed getDefaultNetwork to getLastActiveOrDefaultNetwork for clarity about its fallback behavior
• Modified Wagmi adapter's connect method to use defaultNetwork from OptionsController instead of the chainId parameter
