Parser OFX tolerante ao formato SGML de bancos brasileiros (sem closing tags, BOM, timezone suffix). Parser CSV com separador de campo/decimal configurável. Dedup por FITID (OFX) ou date+amount+desc normalizado. Fluxo: POST /preview → revisão na UI → POST /confirm salva e loga. Migration 002 adiciona external_id com unique index.
