// FiiDiiSubTab — F&O FII / DII content widget. Replaces the placeholder
// for SubTab::FiiDii in FnoScreen.
//
// Subscribes to `fno:fii_dii:daily`. The producer (FiiDiiService) publishes
// the rolling last-30-days window as `QVector<FiiDiiDay>`. The sub-tab
// renders a date-stamped table on the left and a daily net-flow bar chart
// on the right. A REFRESH button forces a producer fetch on demand —
// useful right after market close when the user wants today's number.
