6730a89d7c Hotfix: Resolves connection pool bugs for Redis 
- The previous implementation of the shared Redis connection pool had a critical issue where any Redis storage instance would disconnect the global shared pool upon closing. This caused `ConnectionError` exceptions for other instances still using the pool.
- This commit resolves the issue by introducing a reference counting mechanism in `RedisConnectionManager`.

2ade3067f8 Refac: Generalize keyed lock with namespace support 
Refactored the `KeyedUnifiedLock` to be generic and support dynamic namespaces. This decouples the locking mechanism from a specific "GraphDB" implementation, allowing it to be reused across different components and workspaces safely.

Key changes:
- `KeyedUnifiedLock` now takes a `namespace` parameter on lock acquisition.
- Renamed `_graph_db_lock_keyed` to a more generic _storage_keyed_lock`
- Replaced `get_graph_db_lock_keyed` with get_storage_keyed_lock` to support namespaces
