Tests: pytest-Suite für Konten, Haushalt, Kanban, Reisen und Migrationen
- backend/tests: jede Test-Funktion bekommt eine frische Datenbank; test_migrationen.py baut ältere Datenbank-Stände nach und prüft die verlustfreie Umstellung (auch zweiter Start ohne Änderung) - requirements-dev.txt mit pytest - Fix (von den Tests gefunden): Eine neue, leere Datenbank bekam keine erste Liste "Zuhause"; jetzt einmalig beim ersten Start Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
