This PR adds a streamlined “Export Base Protocol” feature to the Fibsem milling stage editor, allowing users to dump core milling settings into a simplified YAML template.

• Imported a file‐save dialog helper.
• Added an “Export as Base Protocol” button to the widget.
• Implemented export_base_protocol to deep‐copy the current protocol and save it.

• [nitpick] This helper method appears to be private, but isn’t prefixed with an underscore. For consistency with _initialise_widgets, consider renaming to _export_base_protocol.

• The code uses copy.deepcopy but there is no import copy in this file, which will raise a NameError. Please add import copy at the top.
