feat(设备列表): 新增 has_active_package 查询条件

- DTO ListDeviceRequest 增加 HasActivePackage *bool 字段（query/json: has_active_package）
- Service List 方法将 HasActivePackage 透传至 filters["has_active_package"]
- Store applyDeviceFilters 新增 applyHasActivePackageFilter：
  true  → EXISTS 子查询（生效中主套餐）
  false → NOT EXISTS 子查询
  均限制 master_usage_id IS NULL、deleted_at IS NULL，状态使用 constants.PackageUsageStatusActive
