Refactor model structure: update import paths from 'app.modelz' to 'app.models' across multiple files for consistency, remove obsolete 'modelz' directory, and adjust Dockerfile and migration script to reflect these changes, enhancing clarity and organization in the codebase.
Refactor application structure: update model import paths from 'app.model' to 'app.modelz' across multiple files for consistency, and introduce new database models in 'app.modelz.database' to enhance organization and clarity in the codebase.
Refactor model imports across the application: update import paths from 'app.models' to 'app.model' in multiple files, and remove the now redundant models.py file.
