The dataset-info plot remembers the selected quantity and the Grid/Per-image
toggle states across restarts, with grid scans and standard scans each
keeping their own favourite (QSettings groups datasetInfoPlot/gridScan and
/standard). Choices are stored as the combo item's data code, not its index,
so a saved choice survives the plot list changing and a code no longer
offered falls back to the first item. Favourites are saved on every explicit
user action and applied whenever a dataset of the other kind loads; loads of
the same kind keep the in-session state, and the live-source default still
wins until the user picks. The unconditional Grid auto-check on grid scans
moved into the favourite's default, so unchecking Grid on a grid dataset now
sticks.
View > "Reset all settings to defaults" clears the whole settings store after
confirmation and brings the running session to a first-start state in place:
default layout, window size, display settings (Indigo, Auto off, HDR off),
plot choices, and the file manager root. Because the live state then equals
the defaults, saving on close stays enabled and later changes persist as
usual.
File > Quit now closes the main window instead of calling
QApplication::quit(), so closeEvent runs and the persistent settings are
saved on that path too - previously they were saved only when the window was
closed by the window manager.
The file manager root persistence was audited and left unchanged: saved on
every successful change, restored behind JUNGFRAUJOCH_DATA_ROOT, and a
vanished directory falls back to the home directory.
