feat: list sort respects useBalancedRanking toggle

The two existing sort sites (initial init + threshold cutoff) now read
from the local toggle. A second effect re-sorts the list when the
toggle flips, but only when no manual reorder is pinned to the
snapshot — persisted manual reorders always win, matching prior
behavior.
