Pull request overview

This PR implements support for multiple content stores by introducing a ContentStoreRegistry abstraction. The changes enable content references to include an optional store identifier, allowing content to be stored across different storage backends while maintaining backward compatibility with existing single-store implementations.

Changes:

• Introduced ContentStoreRegistry interface and DefaultContentStoreRegistry implementation to manage multiple content stores
• Enhanced ContentReference to support optional store IDs with parsing/serialization logic
• Updated ContentApiImpl, DatamodelApiImpl, and related components to use the registry instead of direct ContentStore references
