Update configuration and directory handling

- Increased time_window in plot_definitions.json from 10 to 60.
- Added external_path function in config_manager.py to handle paths for records and logs, ensuring compatibility with both development and PyInstaller executable environments.
- Updated PLCDataStreamer to use the new get_csv_directory_path method for retrieving the records directory.
- Refactored main.py to include get_records_directory function for consistent records directory path retrieval.
- Modified system_state.json to set should_connect to false and updated last_update timestamp.
