feat(ui): delete plates from the Plates list's right-click menu

Add Delete Plate to the plate row menu beside Duplicate Plate, enabled
when Remove Selected Plate is. Drop the Plates tab's add-plate button
and the Plate menu's Add and Remove items: the list's trailing empty
plate already provides new plates, and removal stays on the tab.
