Fix 500 Error Response in /ping Endpoint

[plural-copilot]

Summary

This pull request addresses an issue with the /ping endpoint in the FastAPI application which causes predictable 500 Internal Server Error responses when the UNIX timestamp is divisible by 3. The code modification proposed will ensure the endpoint reliably returns a successful response without raising errors.

Changes Made

• Modified the /ping endpoint to remove the condition that raises an exception.

Rationale

By removing the behavior that generates internal server errors, we improve the reliability of the service and ensure a consistent response from the /ping endpoint, thus reducing false alerts related to high error rates. This change will stabilize operations and should resolve the current alert situation.
