style(settings): tidy the General panel

Per review: the panel-wide 'saved instantly' hint goes; the date-format picker
loses its embedded sample line (kept as the buttons' tooltip) so the row is one
line tall; the IARU region moves up under the date format, before the themes;
and the parentheticals after Distances-in-miles, Check-updates and the
telemetry opt-out go. The telemetry and ClubLog explanations survive as
tooltips — an opt-out about data leaving the machine, and an option changing
how entities resolve, should still say what they do somewhere.
