Refactor printer config management and OctoPrint integration

Replaces klipper_config_manager.py with printer_config_manager.py for unified printer configuration management. Updates all references and logic to use the new manager, removes in-memory selected_printer_config from PrinterModel, and enhances OctoPrint configuration restoration and printer profile updates. Improves scalability and dynamic extraction of printer settings from firmware files.
