test: Backend-e2e in CI stabil (eigene Jahre, Sperren, ein Server je App)

- daily-evaluation nutzt die Jahre 2011/2012 statt 2001, damit der Job nicht
  die Daten von autopilot und reminders liest und verändert.
- throttler: app.listen(0) einmal je App statt eines Servers je Anfrage
  (ECONNRESET bei 40 parallelen Anfragen).
- outbox-claims: 120 s Zeitlimit für 2000 sequentielle Anweisungen.
- migration-harness: eine `migrate deploy` zur Zeit über eine eigene
  Advisory-Sperre (P1002 bei parallelen Migrations-Suites).
- authority-notices und authority-notices-herd laufen über
  exclusive-suite nacheinander; Herd-Wiederholung räumt eigene Entwürfe.
