feat(settings): add always-show-booking-routes account setting

New map_always_show_routes account setting, defaulting to off, i18n'd
across all 22 supported locales. Lives in Display > Travel & map,
directly under Booking route labels — its closest sibling — using
that section's immediate-save On/Off pattern rather than a separate
toggle+Save flow, since it's a booking-display preference, not a map
render-config option.
