Issue: Submission Upload Error - Insufficient Space Despite Deleted Models

Issue Description

I encountered an error while trying to upload a model for my university exam competition hosted on Codabench. The error message reads:

Steps to Reproduce

Uploaded several models initially without issue.
Requested the competition administrator to delete previous submissions to free up space.
Attempted to upload a new model (file size: 732.7MiB).
Received the error message mentioned above, stating that my available space is negative (-567.9MiB), despite previous models being deleted.

Expected Behavior

I expected to have sufficient storage space for the new model upload after deleting the earlier models. The system should reflect the updated available space correctly after deletion.

Actual Behavior

The system shows a negative available space value, suggesting that either:

The deletion of previous submissions did not properly update the storage quota, or
There is a bug in the storage quota calculation logic.

Impact

Prevents participation in the competition, affecting the evaluation process for my exam.
Creates confusion around storage management in Codabench.

Suggested Fixes

Verify that storage space calculations are updated correctly when files are deleted.
Ensure that the available space reflects real-time changes in user resources.
Provide users with a more detailed view of their storage usage, including logs of deleted and current files, for better transparency.
