🐛 Bug Report

Describe the bug

The backend API container repeatedly restarted because the application failed during startup with an import error in the authentication service. The service imported get_password_hash from the password utility module, but that symbol was missing in the module at runtime, causing process exit and Docker restart loop.

To Reproduce

Steps to reproduce the behavior:

1. Start the backend with Docker Compose.
2. Run docker ps and observe the API container status.
3. Run docker logs <api-container-id>.
4. See error: ImportError: cannot import name 'get_password_hash' from app.utils.password_utils and repeated restarts.

Expected behavior

The API should start successfully, remain in Up state, and authentication routes should load without import errors.

Environment

• OS: Linux
• Browser: N/A (backend startup issue)
• Version: Python 3.13, FastAPI backend in Docker

Additional context

Observed non-blocking warning during startup:

• Warning: Could not initialize LogBull logger: Invalid project ID format ...

This warning does not cause the restart loop. The primary failure was the auth password utility import mismatch.
