test(cluster): refresh grd dump baselines surfaced by nightly

The same S-reconfig nightly that pinned the join-fence wedge also flagged
two stale dump-count baselines that lagged already-shipped counters:

  * t/108 pg_cluster_state pcm category 22 -> 23 (spec-4.6a D12
    dead_cleanup_entries).
  * t/249 grd_recovery dump roster 18 -> 31 keys plus the exact sorted key
    list (spec-4.6 2.4 base + spec-5.16 D5 join direction + spec-4.6a
    liveness/episode surface).

Both stay exact-count / exact-roster assertions; the code already emits the
31-key grd_recovery set (verified against cluster_debug.c).
