Integrate #3/#5/#6 (week-start, time-format, hour-lines) into the agenda range branch. SettingsViewModel folds all five view prefs into one combine; WidgetData keeps the range-based window and adds the resolved is24Hour. Also, in the same Appearance section: - regroup the rows into four titled-by-spacing groups (theme & colour / calendar layout / timeline display / agenda) instead of one long card. - add an explanatory description line under the title of each agenda-range picker (PickerDescription).
