feat: F4.7 the data exchange window, measured against Java's

One row per frame (its highest layer's), Java's detail tree, the table as
Java's text file, "Tabellen löschen" for every card (clearCapture in the
room), a tab per card with Java's title, Java's layer colours as tokens,
the chosen frame and autoscroll per tab. New oracle ExchangeWindowRun.
