// MacroCalendarService — DataHub producer for the upcoming macro/economic
// events feed served by Fincept's API (`api.fincept.in/macro/upcoming-events`).
//
// Topic: `econ:fincept:upcoming_events`. Payload: `QJsonArray` (the events
// array as returned by the API). One topic, one producer, one HTTP fetch
// per refresh — the hub fans out to the EconomicCalendarWidget and any
// future consumers (report builder, MCP tools, agents).
//
// TTL: 5 min. Min interval: 60 s. Both honour the upstream cache and keep
// rate-limit pressure low.
