Add update_available field to checkpoint, embedding, and LoRA service response formatting. The flag indicates whether a model update is available and defaults to false when not specified.
Include comprehensive tests to verify the update flag is properly included in formatted responses and defaults to false when not present in the payload.
- 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.
