Hotels - Booking

Hotel booking creation and management endpoints

📄️ Create booking

Creates a hotel booking. Prefer `input.optionRefId` from `optionQuote.optionRefId` after prebooking. When the connection allows book-from-search (no `RATE_TYPE` remark containing `RECHECK`), you may pass the search option `id` instead. Requires holder and rooms[].paxes.

📄️ Cancel booking

Cancels an existing booking by Bundleport bookingID (optional client/provider references when supported). Response is proto CancelResponse with cancelReference plus audit/errors/warnings — not a nested booking object or cancel penalties payload.
