Updated KPI calculation to output planned and actual weights for each edge for better transparency in the frontend

If a MaximumKPICalculationStrategy or AggregationKPICalculationStrategy has only empty children we set the KPI itself to empty.  This is done by throwing an error which should be caught when calculating the KPI

The actuator endpoint uses the application's management port, which is a new environment variable

updated execution script

added tool type enum for easier identification of tools stored in the db. added ort results for tool run querries

removed legacy endpoint as frontend moved to new endpoints too
