SavedCutTimeSettings reads and writes the cut-time values last used in
Calculate Cut Time or the simulator under the names and text the WinForms
app already stores (LastFeedrate, LastHoleFeedrate, LastRapidFeedrate,
LastPierceTime as invariant decimals, CutTimeSkipEtch "True"/"False",
CutTimeMachine as a machine id or "none"), with each unreadable value
falling back to its WinForms default. It also holds the rules: never-saved
values use the cut-parameter defaults, no hole feed uses the feed, and the
saved machine falls back to the first by name. The WinForms app's
SavedCutParameters and machine box now call it; their behaviour is
unchanged.
