Final Class Passkey-based CrossmintWalletApprovalSigner that delegates signing to a caller-supplied callback. 
final class CrossmintPasskeyApprovalSigner implements CrossmintWalletApprovalSigner
In Stage 1, the callback is always required. In Stage 2, native platform passkey support can be used as a fallback when no callback is provided. Until native support ships, passing a passkey signer config without callbacks throws CrossmintSignerException(code: passkeyCallbackMissing) during wallet creation or signing.
