Preview-render a template payload (Twilio Content Preview parity)
Renders the final outbound payload — WhatsApp template-with-buttons, RCS rich card, SMS/MMS/email body — with positional and Liquid-style variable substitution applied. Returns the rendered shape plus a structured composition_errors array that surfaces the SAME problems the provider would reject on (Meta error_subcode 2388042, RBM INVALID_ARGUMENT), but BEFORE the wire call so no wallet credit is burned. Accepts EITHER a stored template_id or an inline template object for ad-hoc compose previews.
