BUG: Leaked Semaphore Objects with Uvicorn

[kalbfled]

Description

• Ticket is understood, and QA has been contacted (if the ticket has a QA label).

When shutting down the app locally while using only uvicorn, this is displayed:

...va-enp-api$ /usr/lib/python3.12/multiprocessing/resource_tracker.py:254: UserWarning: resource_tracker: There appear to be 16 leaked semaphore objects to clean up at shutdown
  warnings.warn('resource_tracker: There appear to be %d '

The number of leaked semaphores varies.

Steps to Reproduce

Locally, in a terminal:

1. Start the database: docker compose -f ci/docker-compose-local.yml up enp-db -d
2. Run the app: poetry run uvicorn app.main:app --reload
3. After you see, "Application startup complete," press Ctrl-C to shut down the app, and behold the warning.

Impact/Urgency

Low

Expected Behavior

• No warnings during uvicorn shutdown
