UserKeysStorage
Manages persistent storage and retrieval of user key metadata for device binding operations.
This class provides a high-level interface for storing, retrieving, and managing UserKey metadata while abstracting the underlying storage implementation. It handles the complete lifecycle of user key information including creation, lookup, updates, and deletion.
The storage system maintains only metadata about cryptographic keys, not the actual private keys themselves, which remain securely stored in the Android KeyStore.
