fix: Resolve permission error for log file in Docker container

- Change log file location from /app/app.log to /tmp/app.log (writable in containers)
- Add error handling to gracefully fallback to console-only logging if file logging fails
- Update test files (test_logging.py, test_task_type_fix.py) with same fix
- Prevents PermissionError: [Errno 13] Permission denied crashes on startup
