Pull request overview

This PR targets two error cases seen in VERITAS (“vts”) workflows: (1) telescope-footprint computation failing when configured telescopes are not present in an event chunk, and (2) joblib model artifacts being written without post-save validation.

Changes:

• Add a post-save validation step for model joblib artifacts (atomic temp-file write → validate → rename).
• Fix _calculate_array_footprint sizing to use configured telescope IDs rather than only those seen in the current event chunk.
• Extend unit tests to cover the new footprint behavior and model-save validation failure handling.

File	Description
src/eventdisplay_ml/models.py	Writes models atomically and runs a validation subprocess before finalizing the output joblib.
src/eventdisplay_ml/data_processing.py	Uses tel_config["tel_ids"] to size the array-footprint lookup to avoid indexing failures when some configured telescopes are absent in a chunk.
tests/test_models_helpers.py	Updates model-save test inputs and adds a test for rejecting failed validation.
tests/test_data_helpers.py	Adds coverage for footprint computation when a configured telescope is absent from the event telescope list.
