fix(unbound): restart statt reload + DNS Auto-FW-Rules dokumentiert

Browse Source 
Bug: Unbound bindet Listen-Sockets nur beim startup. Bei einer
Mutation von dns_settings.listen_addresses (z.B. neue LAN-IP für
Resolver-Zugriff) hat 'systemctl reload' die Config zwar gelesen,
aber nicht neu gebound — neue IPs blieben tot.

Fix: Renderer ruft RestartService statt ReloadService. ~200ms
Resolver-Downtime beim Save, dafür konsistentes Verhalten für jede
Settings/Zone/Record-Mutation.

Plus configgen.RestartService Helper neu (analog ReloadService),
sudoers im postinst um systemctl restart unbound.service erweitert.

NOTE für DNS-LAN-Zugang: zwei Operator-FW-Rules nötig (DNS-UDP +
DNS-TCP from any to any) wenn der Resolver auf LAN-IPs lauscht.
Aktuell manuell anzulegen — ein Auto-Rule-Generator (analog
NAT-auto-forward) wäre die nächste Iteration.

Version 1.0.36.
