List the tour instances generated by a recurring-master draft. Returns tours whose recurringMasterId equals the given draft id, sorted ascending by Tour.latestStart (the cron-trigger timestamp). This is the draft-centric chronological drilldown; the equivalent flat filter is GET /tours?recurringMasterId={id} (descending by default). Returns 404 if the draft does not exist, and 400 with internalCode: RECURRING_MASTER_REQUIRED if the draft exists but is not a recurring master. Pass from/to (epoch seconds, inclusive) to restrict to a date window.
