Generate a message (nonce)

Generates a unique message (nonce) to be signed by the user's wallet, which is used for verifying wallet ownership.

This process helps ensure that the user attempting to connect the wallet is indeed the owner of the specified wallet address. The generated message (nonce) is returned and should be signed using the user's wallet. The signature will then be submitted to the /connect endpoint for verification.
