Passkeys & WebAuthn
Authenticate
Authenticates the user with an existing registered passkey. Performs a two-step flow: calls POST /sdk/v1/webauthn/authenticate/start/primary (no session) or POST /sdk/v1/webauthn/authenticate/start/secondary (with session) to get assertion options, invokes the platform credential API, then calls POST /sdk/v1/webauthn/authenticate to complete.
