feat: add update service dependency and has_update filter

- Pass ModelUpdateService to CheckpointService, EmbeddingService, and LoraService constructors
- Add has_update query parameter filter to model listing handler
- Update BaseModelService to accept optional update_service parameter

These changes enable model update functionality across different model types and provide filtering capability for models with available updates.
