ha: replace the HAOS VM with a native Podman Quadlet container

Browse Source 
The fixed 2 GiB ha_van allocation starved the 4 GB Pi. HA Container now
runs on the host network (http://10.42.0.1:8123): ha/homeassistant.container
installs to /etc/containers/systemd/, config in /srv/homeassistant, host
D-Bus mounted for onboard Bluetooth (needs apparmor=unconfined — Ubuntu's
dbus-daemon mediates per AppArmor label and denies AddMatch to BlueZ —
plus NET_ADMIN/NET_RAW for habluetooth adapter recovery).

Drop the VM-era plumbing: the 10.42.0.50 dhcp-host pin becomes a
host-record for 10.42.0.1, and the legacy-URL DNAT + hairpin masquerade
go away entirely. ha_van.xml retired to git history.
