anti b57269f68a Add --ipvlan flag for WiFi-compatible deployments
MACVLAN assigns unique MACs per container; WiFi APs typically reject
frames from unregistered MACs, making deckies unreachable from other
LAN devices. IPvlan L2 shares the host's MAC, so all traffic passes
through the AP normally.

- network.py: add create_ipvlan_network, setup_host_ipvlan,
  teardown_host_ipvlan, HOST_IPVLAN_IFACE
- config.py: add ipvlan: bool = False to DecnetConfig (persisted to
  state so teardown uses the right driver)
- deployer.py: branch on config.ipvlan for create/setup/teardown
- cli.py: add --ipvlan flag, wire into DecnetConfig
- tests/test_network.py: new test module covering ips_to_range,
  create_macvlan/ipvlan, setup/teardown for both drivers
