The IoT VLAN advertises a global IPv6 prefix (RA/SLAAC), but the Atom Echo
ran v4-only because ESPHome defaults IPv6 off. Enable it so the device is a
proper dual-stack citizen of the segment and has a real global IPv6.
This is the prerequisite for the DNS-side fix: once the device has a real
AAAA, a `unifi_dns_record` AAAA for shelly-ble-proxy-1.iot.renner.uno can be
pinned to it (same pattern as the existing udm/captive records in
opentofu/dns_renner_uno.tf), so the name resolves to the device instead of
falling through to the *.renner.uno proxy wildcard.
Takes effect on the next USB re-flash (no OTA on this device by design).
