Tickets: Transcript beim Schließen + Thread-Löschung

- Schließen-Button erstellt jetzt ein Text-Transcript (chronologisch, inkl.
  Attachment-URLs, max 500 Nachrichten) und schickt es dem Ersteller per DM
- Kopie ins Mod-Log (Aufbewahrung fürs Team, mit Hinweis falls DM blockiert)
- Thread wird danach gelöscht statt nur archiviert (Fallback: sperren+archivieren,
  falls dem Bot Lösch-Rechte fehlen)
