Add vehicle management features in Falukant

- Introduced vehicle types and transport management in the backend, including new models and associations for vehicles and transports.
- Implemented service methods to retrieve vehicle types and handle vehicle purchases, ensuring user validation and transaction management.
- Updated the FalukantController and router to expose new endpoints for fetching vehicle types and buying vehicles.
- Enhanced the frontend with a new transport tab in BranchView, allowing users to buy vehicles, and added localization for vehicle-related terms.
- Included initialization logic for vehicle types in the database setup.
