This commit adds relationships to link Pucks and Samples to Beamtime in the models, enabling better data association. Includes changes to assign beamtime IDs during data generation and updates in API response models for improved data loading. Removed redundant code in testfunctions.ipynb to clean up the notebook.
Introduce new endpoint and model for managing beamtimes, including shifts and user-specific access. Updated test scripts and data to reflect beamtime integration, along with minor fixes for job status enumeration and example notebook refinement.
