Transfer modal now only appears when a Hall of Fame team is selected,
using the existing hofTeam data instead of the survivors endpoint.
Without a HoF selection, advance proceeds directly with no transfer step.
Transferred encounters are now a separate category: they appear in their
own "Transferred Pokemon" section, don't occupy route slots in the
encounter map, and don't block the route-lock check (excluded via
genlocke_transfers subquery). The run detail endpoint returns
transferEncounterIds so the frontend can distinguish them.
