fix(d1): Calendar-Suite + ai_proactive repariert — conftest CalendarPlugin-Import wiederhergestellt (abbe7a1-Regression), CalendarContract-Zugriffe snake_case→PascalCase (context_tools, services ×2, mail/routes), 2 stale Rate-Limit-Tests auf zentrale check_rate_limit-Grenze umgestellt; test_calendar 34/34, ai_proactive-Failures behoben; Mail-Vorbestand dokumentiert
