Backend: - Modelle + Migration 0002: accounts, account_identifiers, category_groups, categories, transactions, exchange_rates (alle owner-gescoped). - EZB-Kursdienst (90-Tage/Historie) + Backfill-Skript; Umrechnung EUR<->CHF zum Buchungsdatum mit lokalem Cache und manueller Übersteuerung; EUR-Pivot (amount_eur_cents) eingefroren. - Kontostände + Netto-Vermögen (Umrechnung in Hauptwährung). - Router: accounts (inkl. IBAN-Identifikatoren), categories (Gruppen+Kategorien), transactions (Ausgabe/Einnahme/Transfer, cross-currency), rates. - Gruppierte Standard-Kategorien je Nutzer beim Anlegen. - pytest-Suite: Währung, Salden, Cross-Currency-Transfer, Nutzer-Isolation. Frontend: - Seiten Konten, Kategorien, Buchungen; Icon-Chip, Geldbetrag mit Umrechnung, Icon-/Farbwähler, Modal; erweitertes SVG-Icon-Set (Konto-/Kategorie-Icons). - Währungs-/Datumsformatierung (EUR de-DE, CHF de-CH), i18n DE/EN erweitert. - Live-Umrechnungs-Vorschau im Transfer-Formular.
