Start creating a passkey

Step one of registering a user with a passkey — Face ID, Touch ID, Windows Hello or a hardware key. No password, nothing to remember, nothing to phish. Convert the JSON response into the binary values WebAuthn expects, then give it to the browser: ```js const optionsJSON = await fetch('/wallets/connect/passkey/register/options') .then(r => r.json()); const options = PublicKeyCredential.parseCreationOptionsFromJSON(optionsJSON); const credential = await navigator.credentials.create({ publicKey: options }); ``` Then serialize the result with `credential.toJSON()`, add the required `organization_id`, and send it to `POST /wallets/connect/passkey/register/verify`, which creates the wallet and signs them in. No sign-in needed — this is how a new user signs up.
