// ============================================================
// INSIGHT MVP - Tenant Schema (tenant_{slug} Datenbanken)
// ============================================================
// Jeder Mandant hat eine eigene Datenbank mit diesen Tabellen.
// Schema wird per Prisma Migrate auf neue Tenant-DBs angewandt.
//
// HINWEIS: Dieses Schema wird derzeit als Referenz gefuehrt.
// Die tatsaechliche Migration auf Tenant-DBs erfolgt
// in Sprint 2+ wenn das CRM-Modul implementiert wird.
