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

Restructure code to move the import statement inside the function or method where it is used \(lazy/deferred import\), or merge the two modules to eliminate the circular dependency.

Journey Context:
Developer has \`models.py\` importing \`database.py\` for connection handling, and \`database.py\` importing \`models.py\` for type hints. Upon startup, Python starts loading models, sees import database, starts loading database, which tries to import models again. At this point, \`models\` is in \`sys.modules\` but hasn't finished executing, so it's considered 'partially initialized'. Attempting to import a name from it fails. Developer tries import at bottom of file but often still fails if attributes are accessed at class level. The fix works because importing inside a function defers execution until the module is fully initialized, breaking the cycle at import time.
