Combinable event-contract events and the MVC ticker that must

GET /api/v1.0/quote/valid-combos

List combinable event-contract events and the MVC ticker that must be passed through to RFQ. Returns combo_events[] with event_code, event_name, combo_contracts (KS symbols), series_code, category / competition / competition_scope; data.mvc is the opaque RFQ passthrough; pagination has completed / page_flag / count. Public symbols use KS.{futu_symbol}, not the OpenD EC. prefix. No subscribe required. For combo RFQ use quote.combo_quotes and pass mvc through unchanged.
