Subject: [PATCH] feat: persist plate optimizer settings across autonest runs

Add LoadPlateOptions() method to AutoNestForm that restores saved plate
options and salvage rate from the Nest. Call this method in
RunAutoNest_Click when opening the dialog if saved options exist, and save
settings back to Nest after dialog completion.
