feat: Complete Company Migration Project and Fix Autocomplete Issues

- Implemented a comprehensive migration from a single Company model to specialized entities (Operators, PropertyOwners, Manufacturers, Designers).
- Resolved critical issues in search suggestions that were returning 404 errors by fixing database queries and reordering URL patterns.
- Conducted extensive testing and validation of the new entity relationships, ensuring all core functionality is operational.
- Updated test suite to reflect changes in entity structure, including renaming fields from `owner` to `operator`.
- Addressed display issues in the user interface related to operator and manufacturer information.
- Completed migration cleanup, fixing references to the removed `companies` app across migration files and test configurations.
- Established a stable testing environment with successful test database creation and functional test infrastructure.
