"""`trades_db.py --report` non stampa piu' un bonifico come rendimento (debito #14, 2026-09-02).

Il numero che stampava era `e1/e0-1` sulla serie grezza: «+243%» per il 96,3% un versamento.
Il report ora CHIAMA `journal.rendimento_twr` (P1: non rifa' il conto). `T.connect()` nudo
finisce in tmp grazie alla fixture autouse di conftest: qui non si tocca il libro vivo.
