fix: require --compactFile in CKF, GNN, and geometry-visualization options

BEGINRELEASENOTES

• Fixed a cryptic Gaudi TypeError/ValueError when --compactFile was omitted in CLD_CKFTracking.py, runGNNTrackFinding.py, and test_visualize_acts_geo.py by making the argument required, with a clear error message.

ENDRELEASENOTES

Summary

--compactFile was optional in several options scripts. When omitted, the resulting None reached GeoSvc's detectors property as [None], which failed deep in Gaudi's PropertyProxy._isCompatible with a cryptic TypeError: NoneType takes no arguments / ValueError: received an instance of <class 'NoneType'>, but <class 'NoneType'> expected for property detectors.

Marking --compactFile required=True in the three affected scripts fails fast with a readable argparse error instead.
