sync: Inventory-Realabgleich + neue host_vars/roles/playbooks

Nachgezogener Arbeitsstand des Homelabs:
- neue host_vars (k3s-*, gluster-*, docmost, paperless, kometa, thelounge, satisfactory, wolfstack-vm)
- neue Rollen/Playbooks (net_watchdog, patchmon-agent, tc_ratelimit, sops-age, rotate-ssh-key, dns-doh, remove-postfix, checkrr-deploy)
- diverse Rollen-Updates (base, borg, dns_resolver, frp_client, hawser, nvidia)

Ausgeklammert (bleiben uncommittet): host_vars/docmost/vars.yml (Klartext-Token -> sollte vault-konform via vault_* referenziert werden).
