Key changes:

• Added backend endpoint export_params_to_file to handle parameter export requests
• Implemented exportParamsToFile method in ParamsController to write parameters to file
• Added frontend UI button and Redux action to trigger parameter export
• Refactored IPC channel name from missions:get-save-mission-file-path to generic app:get-save-file-path for reusability
