feat: Implement general catalogs for ports, unit conversions, and units of measure

- Added models, DTOs, services, and routes for ports, including CRUD operations.
- Introduced unit conversions with corresponding models, DTOs, services, and routes.
- Developed units of measure with detailed models, DTOs, services, and routes for various types.
- Ensured all new features are integrated with FastAPI and SQLAlchemy for seamless database interactions.
