The stored list only re-merged + re-sorted periodically under the "recent"
sort; under distance sort it refreshed only on entry. So a [LOC] share
arriving while the list was open (sorted by distance) wasn't re-sorted and
the now-nearest node never moved to the top. Refresh on a timer under both
sorts, keeping the highlighted node selected across the rebuild. Factor the
identity-preserving reselection into refreshKeepingSelection(), shared by
the list and the detail/nav refresh paths.
Verified: WioTrackerL1_companion_solo_dual builds clean.
