Start the authentication process by sending an OTP to the provided email address. Includes automatic provider fallback: if the requested provider (default: Privy) is unavailable or times out, the endpoint falls back to the alternate provider. When a fallback occurs, the response includes requested_provider (the originally requested provider) and fallback_reason (timeout or provider_error).
