[bug\_fix] ImportError: cannot import name 'X' from partially initialized module 'Y' \(most likely due to a circular import\)

Refactor to remove the circular dependency, or move the import statement inside the function/method where it is used \(lazy import\) to defer execution until both modules are fully initialized.

Journey Context:
Developer has 'models.py' and 'utils.py'. 'models.py' imports 'utils.helper' and 'utils.py' imports 'models.MyModel' for type hints. When running the app, they get 'ImportError: cannot import name MyModel from partially initialized module models'. They try reordering imports at the top of the files but the error persists or moves. They learn about circular imports: when models starts loading, it hits import utils, which tries to import models, but models is only partially initialized \(it's currently executing its top-level code\). They fix it by moving the 'from models import MyModel' inside the function in utils.py that actually uses it, so the import happens at call time when both modules are already loaded.
