Pull request overview

This PR introduces service layer entities for pipelines and model revisions, moving them from the schemas layer to the models layer. This refactoring centralizes domain entities and removes redundant mapper classes.

Key Changes:

• Created Pipeline and ModelRevision entities in the models layer with validation logic
• Moved PipelineStatus and TrainingStatus enums to the models layer
• Replaced mapper classes with direct model_validate() calls for entity conversion
• Introduced API-specific view schemas (PipelineView, ModelView) that adapt service layer entities for API responses
