The storage crate had its own RetryConfig struct (max_attempts, initial_delay, max_delay, backoff_multiplier) duplicating common::resilience::retry::RetryConfig. Added backoff_multiplier field to common's RetryConfig and updated storage to re-export and use common's version with its field names (max_retries, base_delay). Updated all storage tests accordingly.
