- Updated GBultoService to use models.Package instead of models.GBulto. - Refactored Part model to use SQLAlchemy 2.0 style with Mapped and mapped_column. - Added timestamps (created_at, updated_at, deleted_at) to various pedimento models. - Improved relationships and foreign key constraints in pedimento models. - Updated PermissionRuleOct and Seal models to use Mapped and mapped_column. - Changed DTO configuration from orm_mode to from_attributes for better compatibility. - Removed obsolete models (models.py and models_ped.py) from the repository.
