/**
* reports-view.js — Due-Diligence Reports
*
* 1. Accounts Receivable Aging (Stichtag frei wählbar)
* 2. Invoice-Level Revenue (Zeitraum frei wählbar, optional nach Monat gruppiert)
*
* Beide Reports können Kundennamen pseudonymisieren. Die Anonymisierung passiert
* ausschließlich serverseitig — dieses Modul bekommt bei aktiver Option gar keine
* Klarnamen zu sehen und kann sie folglich auch nicht in ein CSV schreiben.
*
* Beträge kommen als numeric-Strings vom Server und werden nur zur Anzeige
* formatiert. Ins CSV gehen die Rohwerte, damit Excel sauber rechnen kann.
