Pull request overview

Adds a new Yadro (Tatlin FCVolume) storage backend implementation to Sunbeam and integrates it into the existing backend test suite/fixtures so it is discovered and validated alongside the other backends.

Changes:

• Introduce YadroBackend and YadroConfig (with protocol validation via an enum).
• Add unit tests for the Yadro backend and config validation.
• Update shared backend test fixtures and common “all backends” tests to include Yadro.
