/*
  Struttura del P&L del Cash Flow. Le etichette sono quelle di oggi (cashFlowRowDefinitions in CashFlow.tsx):
  non si traducono e non si rinominano.
  La riga "Total …" di ogni sezione diventa l'intestazione della sezione stessa (con il totale), come nel design.

  drill: categoria e tipo passati a /transactions quando si clicca un importo.
  !! Claude Code: allinea questi valori a quelli che CashFlow.tsx passa oggi a <DataRow categoryName transactionType>
     nella vista mensile. Se differiscono, vince il codice attuale.
