fix: update error handling in manage.py 💡

This commit refines the error handling in the `manage.py` script. Specifically, it captures and logs the exception message when an `ImportError` occurs during application import. This provides more detailed logging and helps in diagnosing issues related to application loading. Additionally, it updates the `ruff` configuration to include a new check for try/except blocks (`TRY400`).
