Data Submission Reports Feature

[akuny]

Changes

• Added a migration to update the data_submissions table that creates a new JSON field for storing report data.
• Added a report property to the DataSubmission entity.
• Added DTOs and related utilities for managing report data.
• Updated the task queue to execute additional report logic and persist the results to disk.

Fixes

• Addressed issues with the handling of SQLAlchemy sessions within ApplicationContext implementations and repository implementations.

Future Considerations

• Task Queue Improvement: The current task queue execution blocks the invoking use case from completing. This must be updated so tasks run truly asynchronously in the background in the near future.
• Dev Deployment: This needs some care and attention--presumably after the report frontend is built. In particular, the Celery setup that's currently in place won't work in dev.

Looks great - sorry for the delay

Future thought - it might be helpful to have a way to provide a mock implementation to create_app_context (or maybe create_test_app_context - if this was done often.

Good point, we will almost certainly need to do this sort of mocking a number of times.
