feat(PROJ-21): Phase 2+3+5+8 Multi-Tenancy + PROJ-2 EML/MBOX Upload

Browse Source 
Phase 2a: userstore domain_admin/superadmin Rollen, User.TenantID,
          ListByTenant, UpsertLDAPUser mit tenantID
Phase 2b: storage.Save() mit tenantID *int64, email_refs Tabelle,
          GetTenantForMail, GetAllIDsByTenant, StatsByTenant
Phase 2c: JWT-Claims tenant_id/tenant_slug, Session.TenantID,
          Login Domain-Erkennung via E-Mail-Domain
Phase 3:  tenantMiddleware, Handler-Filterung (Users, Mail, Stats)
Phase 5:  SMTP Domain-Routing via DomainToTenantFunc Callback,
          config smtp.tenant_routing + default_tenant_id
Phase 8:  archivmail migrate-tenants Subkommando
PROJ-2:   Upload-Seite /admin/upload mit DropZone + Progress-Polling
