fix(cluster): Alle Placeholder-Rows bei autoRegister bereinigen

AgentRegisterPeer löschte bisher nur den neuen prenode-{fqdn}-Placeholder.
Alte pre-{timestamp}-Rows (aus Versionen vor 1.1.158) blieben stehen und
zeigten dauerhaft status=joining.

Fix: DeletePlaceholdersByFQDN löscht ALLE ha_nodes-Rows mit gleicher FQDN
außer der echten Node-ID — unabhängig vom ID-Format.

Auch preRegisterByFQDN nutzt jetzt das stabile prenode-{fqdn}-Format.
