feat(ui): wire list-handler nextPhase through the handoff hub event

HandoffRequested now carries nextPhase end to end (IWorkerClient ->
WorkerClient -> MissionControlViewModel -> GetMergeHelperHandoffLaunchSpecAsync),
and the outgoing tile is left open on handoff instead of being closed --
lookups that need the active pane for a task now use LastOrDefault since a
handler task's ConPtySessions can hold more than one pane.
