Add "Save CSV and Open" to the "vs. coordinate" muscle plotter

[adamkewley]

Estimate: 0.25-0.5d

The muscle plot widget has an export CSV but, to match other plots (e.g. those in the simulation screen) it should perhaps also have an export CSV and save option. Here would be the affected area:

The change would be to add an extra ImGui::Menu in ModelMusclePlotPanel around here:

• https://github.com/ComputationalBiomechanicsLab/opensim-creator/blob/main/src/OpenSimBindings/Widgets/ModelMusclePlotPanel.cpp#L1934

And the code would be the same as export CSV, but it would also need an extra function call to open the relevant application. This is done in SimulatorTab currently like this:

                if (ImGui::MenuItem("as CSV (and open)"))
                {
                    auto p = osc::TryPromptAndSaveAllUserDesiredOutputsAsCSV(*this);
                    if (!p.empty())
                    {
                        osc::OpenPathInOSDefaultApplication(p);
                    }
                }

Dropping from 0.4.1 - a few new bugfix tickets (e.g. #645, #644) pushed time out of the schedule and I need to drop ~3 days of development time from the milestone.
