Extract common key-value storage operations into internal/storage/kvtpl/ template directory. This consolidates duplicated logic from both leveldb and inmemory implementations into reusable generic functions. Key changes: - Create kvtpl/ package with generic KV storage operations - Consolidate iterator implementation using generics - Update migration functions to use new template structure - Refactor tests to work with new storage interface This prepares the codebase for easier addition of new storage backends by providing a consistent template layer.
