feat: refactor model API structure to support specific model types with dedicated API clients for Checkpoints, LoRAs, and Embeddings

refactor: consolidate model API client creation into a factory function for better maintainability
feat: implement move operations for LoRAs and handle unsupported operations for Checkpoints and Embeddings
