starknet_patricia_storage: add config field to rocksDB storage

[nimrod-starkware]

Note

Low Risk
Small, additive change that only stores extra state and doesn’t alter read/write behavior or on-disk data handling.

Overview
RocksDbStorage now retains a copy of the passed RocksDbStorageConfig via a new private _config field, and RocksDbStorage::new populates it when constructing the storage.

No behavior changes are introduced yet; this mainly preserves configuration state for potential future use (e.g., toggles like spawn_blocking_reads).
