fix: CSV base data export (#343)

* fix: The import of JSON from third-party providers has been simplified - or allowed. If no node has a port or if all ports are empty or no TrainrunSection has a path, then the import should be adjusted so that all nodes are created and then each train is inserted section by section. This makes the import (exchange) from 3rd party more easy.

* fix: documentation

* fix: title JSON-Based Data Import from 3rd Party Data Providers

* fix: export CSV was broken, header missed two fields (region, IPV)
