Zeigt je Konto Anfangssaldo, Einnahmen, Ausgaben und beide Transfer- Richtungen einzeln, dazu mehrfach gebuchte Auszüge und doppelte Buchungen. Damit lässt sich ein falscher Saldo auf seine Ursache zurückführen, statt sie zu erraten. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

"""Schlüsselt auf, woraus sich jeder Kontostand zusammensetzt.

Saldo = Anfangssaldo + Einnahmen - Ausgaben - Transfers raus + Transfers rein.
|
||
Stimmt ein Kontostand nicht, liegt es fast immer an einer dieser fünf Zahlen –
|

oder an einem doppelt eingelesenen Auszug. Beides zeigt dieses Skript.
