Pete news code-review fixes: realm-first ordering, parked-row reap, death-emit gate

- emitZoneClearNews: claim realm-first before the name guard so an unnamed
  straggler's first clear seeds news_realm_firsts (else the next named
  clearer is mis-announced as first-ever). Mirrors backfillZoneFirsts.
- RunMaintenance: reap permanently-parked pete_emit_queue rows (unsent,
  >30d) so a durable Pete outage can't accrete rows forever.
- emitDeathNews: gate on Enabled()/newsEmissionOn() before the char DB
  reads; markAdventureDead fires per-member on party wipes + in the sim.
