Fix host1 interface config for ifupdown-ng syntax

Changed to ifupdown-ng compatible bonding syntax:
- bond-slaves → bond-members
- bond-mode 4 → bond-mode 802.3ad
- bond-lacp-rate 1 → bond-lacp-rate fast
- Removed bond-slaves directive (handled by bond-members)
- Removed vlan-raw-device (ifupdown-ng auto-detects from interface name)
