* fix: activate Tenant.Default when no tenants configured (Option C)
Ensures IStartupTask implementations (e.g., PopulateRegistriesStartupTask,
RunMigrationsStartupTask) run when multitenancy is enabled but the tenant
provider returns an empty list.
- In DefaultTenantService: treat empty provider response as [Tenant.Default]
in GetTenantsDictionaryAsync (initial load) and RefreshAsync
- Logic is internal to tenant service; no explicit call required
