Pull request overview

This PR adds a new filesystem snapshot dataplane schema and storage layer for the disk manager. It introduces a YDB-backed storage implementation for managing filesystem snapshot metadata, including creation, deletion, locking, and lifecycle management operations. The implementation follows patterns established in the existing snapshot storage module.

Key Changes

• Introduces FilesystemSnapshotMeta storage interface with YDB implementation supporting snapshot CRUD operations and locking mechanisms
• Adds database schema with tables for filesystem snapshots, node metadata, and deletion tracking
• Provides comprehensive test coverage for all storage operations including idempotency, locking, and deletion workflows
