Andreas WredeandClaude Fable 5 a7819edbc2 ha: bridge the Home Assistant VM onto br0 as a first-class LAN device
The VM lived on libvirt's default NAT net (192.168.122.50) behind a
/etc/libvirt/hooks/network hook that inserted FORWARD accepts above
libvirt's REJECT. libvirtd restarts re-inserted its chains on top
without firing the hook, silently cutting clients off from HA.

Now the VM's NIC (virtio, was e1000) bridges into br0: pinned lease
10.42.0.50 / name 'homeassistant' via van-ap dnsmasq, mDNS discovery
works, and no firewall hook can rot. Legacy http://10.42.0.1:8123
kept working via DNAT + same-subnet hairpin masquerade. Hook, libvirt
DHCP reservation, and iptables rules removed; domain XML in ha/.
