Enhanced HafeleClient with timeout and retry logic

 - Added a timeout parameter to HafeleClient initialization.
 - Updated retry_with_backoff decorator with base_delay, max_delay, and jitter_range for improved retry logic.
 - Adjusted total_delay calculation to ensure it respects the base_delay.
 - Modified client initialization in config_flow to include a timeout.
