fix: resolve broken migration dependencies and references after company app removal

- Updated migration files to remove references to the old `companies` app and replace them with new app dependencies (`operators` and `manufacturers`).
- Fixed foreign key references in migration files to point to the correct models in the new apps.
- Updated import statements in management commands and test files to reflect the new app structure.
- Completed a thorough validation of the migration system to ensure full functionality and operational status.
