pool: sync-gate job creation, retry failed payouts; widen nostr relay set

- RebuildJob: no jobs with zero peers or a tip older than 30min;
  mining unsynced produced orphaned blocks and payouts that can
  never be paid (observed in production: 8 orphan 'found blocks')
- payout exec: on SendMoney failure requeue with 60s backoff, up to
  30 attempts, instead of silently forfeiting the payment
- nostr: add oxtr.dev, nos.social, fmt.wiz.biz, current.fyi, nostr.bg
  (12 relays total) for announcement redundancy
